Food Waste

Secret Soup Society: fighting food waste and feeding families

Siân Kidd writes about how a muddy encounter with a group of children at a holiday supper and play session at The Vench inspired the name of Secret Soup Society. Ingenious, yet simple, the voluntary organisation turns ‘veg on the edge’ into nourishing and delicious soup to fight food waste and feed families. We also hear from volunteer Delfina who shares her ‘Full of Beans Soup recipe.

Secret Soup Society fights food waste and feeds families. We make soup using food destined for landfill and redistribute surplus food and goods to organisations fighting food inequality. To date, we’ve served over 2000 portions of soup, saved about three tons of food from landfill and have a team of 10 volunteers who regularly come and cook, or rescue, food.

When I started the project in September 2020, I thought I knew a fair bit about food waste, I’d just finished a year-long course in Practical Sustainability with Shift Bristol, and we’d spent a lot of it talking (and complaining) about the UK food system. I knew that the UK produced around 9.5 million tons of food waste a year, but even so, when I started collecting surplus food from supermarkets for redistribution to FOOD Clubs during lockdown, I was truly shocked at how much there was. I thought food destined for landfill would have something wrong with it, but most of what I was collecting was fine, so why were supermarkets throwing it away? It made me question what food waste really was, why there was so much of it and what I could do about it.

I’d spent the past 16 months working for The Vench, a community centre and adventure playground in Lockleaze, who provide free meals to local children and families at holiday lunch clubs and weekly play sessions. They also run a weekly ‘Food Club’ in partnership with Family Action and Fareshare South West, providing local people ‘good-quality food at a low cost’ by redistributing food that would have been sent to landfill, some of which was the food I was collecting. According to the 2019 index of multiple deprivation, Lockleaze ward is amongst the 10% of most deprived neighbourhoods in the UK, it is also considered to be a ‘food desert’, meaning it is a difficult area to access affordable, quality food, so these services are essential and became lifelines for many when the pandemic hit.

I noticed there were often vegetables left at the end of FOOD Club, crates of ‘veg on the edge’ like floppy carrots, ‘ugly veg’ like celeriac or ‘fiddly veg’ like artichokes or pumpkins. It seemed such a shame to let them go to waste after they’d already been rescued once, so I started to wonder how they could be put to better use than being turned into compost.  During one of the holiday supper and play sessions, I was playing with a group of children in the mud kitchen, when one of them came over with a pot full of muddy water containing floating bits of conker, grass and daisies. They proudly presented me with some ‘secret soup’… and there it was, a brilliant solution to the unused veg problem and a brilliant name to boot as we never knew what ingredients were going to turn up each week needing to be used. I got a load of second-hand cooking equipment, bought some basic ingredients and, the following week, my partner Jacob and I cooked our first batch of soup using Food Club’s surplus veg, and the Secret Soup Society was born!

Now, our volunteers meet once a week to cook soup from the surplus food we collect, and are donated, every week from local supermarkets and brilliant organisations like the Avon Gleaning Network (previously Bristol Gleaning Network). We have some exciting things planned for the coming year: we’re developing our school workshops after a successful trial last summer and in March we will be doing the first of four Community Feast events for Lockleaze residents at The Vench. Our aim this year is to set up as a Community Interest Company, and I’m currently receiving support to do that through the School of Social Entrepreneurs’ ‘Lloyds Start Up Programme’ which I was lucky enough to get a place on last year.

“I love your soup, sometimes I think, will I like that? And then I try it and I do!” Lockleaze FOOD Club member.

Food doesn’t just nourish us, it brings us together and when we work together, we can make real, lasting difference to communities. Our vision is a sustainable food system where everyone has equal access to the food that we all deserve and we’re hoping to get there, one bowl at a time.

If you’d like to make us a donation, you can donate us the price of a coffee via Ko-fi.

If you would like to volunteer with us, you can sign up through the Bristol Can Do website: either soup making at The Vench or food collection for the Secret Soup Society.

Meanwhile, here are our tips to help reduce food waste in the home:

  • Check your fridge, cupboards and freezer before going shopping to avoid buying more than you need.
  • A use-by date relates to food safety, a best-before date relates to food quality, so check your labels before your throw food away.
  • Love your leftovers! So many delicious things can be made from them from, croutons to curry, pickles to sauces and especially, soup! Why not try this simple, delicious soup recipe from our lovely volunteer, Delfina?

‘Full of Beans Soup’ by Delfina

'Full of beans' soup

This delicious, comforting soup is a great belly-filler for chilly winter days. Pumpkin seeds are often thrown away, but they are full of nutrients and easy to turn into a tasty addition to soups and salads. This recipe can be easily modified and turned into a larger chilli by adding chunks of roasted sweet potato and a teaspoon of chilli flakes.

Serves 4-6


2 tablespoons oil
2 chopped onions 
2 teaspoons ground cumin
2 teaspoons smoked paprika
2 teaspoons dried oregano
4 cloves minced or grated garlic 
2 tablespoons tomato purée
400g can chopped tomatoes
2 x cans 400g mixed beans, rinsed and drained 
600ml vegetable stock
2 roasted red bell peppers, chopped
½ teaspoon dried chilli flakes (optional)
salt and pepper, to taste
small handful pumpkin seeds, to serve


  1. Heat the oil in a large pan over medium-high heat, then add the onions and cook, stirring often for 3 minutes, or until the onions are translucent but not browned.
  2. Add the cumin, smoked paprika and oregano, coat the onions and cook for a further minute.
  3. Add the garlic and cook for a further minute.
  4. Stir in the tomato purée until it has coated the onions, then add the chopped tomatoes and stir to combine all ingredients and cook for 3 minutes.
  5. Add the mixed beans, vegetable stock and the roasted peppers.
  6. Bring to the boil, then reduce the heat and simmer for 12-15 minutes, stirring occasionally. Taste and season with salt and pepper. Add dried chilli flakes (if using).
  7. Wash the pumpkin seeds in a sieve and then boil them in a pan of salted water for 10 minutes, or until they all change colour.
  8. Toss in a little oil and sprinkle with salt and roast in a medium-heat oven until they are golden-brown and crunchy.
  9. Serve the soup with a sprinkle of the roasted pumpkin seeds and a hunk of bread, or, for a non-vegan option, add a little handful of grated cheese and a blob of sour cream and enjoy!
