I know everyone says making soup is easy and delicious - sorry, but I don't agree. Don't like it, like something to chew on, and I make rotten soup anyway. I haven't time to cook either. I have a slow cooker so I can maybe use that.
Dont know if this helps, but I make a huge vat of veggie soup in my pressure cooker. I put in carrots, onions, swede, leeks, celery and a tin of tomatoes plus some puree with some chopped lean bacon and a couple of pints of veggie stock. Bring it up to steam and let it do its thing for half an hour. When its de-steamed, take the lid off, just mash the veggies with a potato masher, leaving as many large bits as you want. THEN add a tin or two (depending on the amount of soup you have) of baked beans. Warm it thoroughly again, and season. Its ready then to use. It freezes beautifully and is virtually syn free on the SW diet. WARNING......It can be a bit "windy" due to the veg and beans, so dont eat it before a first date!
