These are a couple of good ones from my Scottish Slimmers recipe cards and as both are "free" food they are low in fat and calories. Have tried both and they are yummy, freeze well and dst enjoy them too -
French Onion Soup
450g onions, sliced
900ml beef stock
pepper
Put onion slices in a large saucepan with 2 tbsp water. Cover and cook gently 10 minutes (check as might need a tiny bit more water.) Stir onions , add another 2 tbsp water, cover and continue to cook gently for 10 min more. Remove lid, turn up heat and stir-fry until water has evaporated and onions gone golden brown. Stir in beef stock and warm through - season with fresh ground black pepper.
Roasted Squash & Red Chilli Soup
1 x 700g butternut squash, deseeded and cut in half
2 medium onions, peeled and quartered
1/4 - 1/2 tsp cumin
900ml chicken or vegetable stock
Olive oil
1 red chilli, de-seeded and finely sliced (or use chilli powder to your liking.)
Preheat oven gas 8. Place squash in a roasting dish together with the onions, drizzle with a little olive oil and bake 45-60 minutes. When cool enough to handle, scoop out squash flesh and blend together with the onions with a blender or processor. Add cumin to taste and enough stock to blend to a puree.
Stir-fry the sliced chilli with a little olive oil for 1-2 minutes in a large saucepan then add puree with remaining stock. Bring to a simmer and cook gently about 5-10 minutes to allow flavours to develop. Stirring often.
