I'll add to the choir of soup-cookers and advocates

Even opening a can of diced tomatoes and putting some pepper, chili, low fat sour cream and maybe oregano in it is bound to be healthier and much tastier than the ready-made variety. Chicken or vegetable broth with elbow pasta, frozen veggies and a can of nay beans = voila, Pasta e Fagioli.
And once you're curious enough to move past cans - that's where the real fun begins. This month, I've cooked spicy pumpkin coconut soup, lean Irish stew and an absolutely amazing Wasabi Split Pea soup that I just cooked up yesterday and that should see us through half the weekend.
If it must be cans - I picked up some Campbell Select Harvest varieties for emergency backup when they were on sale, and they're not too bad if you add a few spices and maybe some frozen veggies.
