I have been asked for the roasted squash, pepper and sweet potato soup recipe. Chris didn't use a recipe (unlike me who always has to follow a recipe), but here is a sort of recipe.
He roasted a squash, onion, peppers, tomatoes and garlic in the oven, until they were softened, having drizzled them with a little oil (or Frylight). He then chopped up sweet potato and ordinary potato and added the roasted veg into a pressure cooker and added vegetable stock. He let it cook for 5 minutes (this could all be boiled in a large pan for about 20 mins (that's the way I would have to do it, because pressure cookers scare me!). As I am fussy (!) he then blitzed the soup down until smooth, although if you like chunky soup, you can leave the chunks in. He probably added a little butter, some salt and pepper and some wine too.
It does taste lovely!
