This simple, tasty soup is a great way of using up produce from the veg patch or veg box. The key to getting everything cooked at the same time is to make sure the carrots and squash are chopped into even, smallish cubes
1. Warm a saucepan over a medium-low heat and add the butter and olive oil. Sweat the onions in the pan until soft but not coloured, about 10-15 minutes.
2. Add the stock, carrots, squash and runner beans. Bring to boil and simmer for 15-20 minutes until all the vegetables are tender, but only just.
3. Adjust the seasoning with a little salt and pepper and serve with a trickle of olive oil over each bowl.
