Look at
www.kraftrecipes.com and other brand name websites. In my experience, they are tasty, relatively few ingredients and regularly use entire packages in the recipe. And when I've used them (I've used TONS of Campbell's soup recipes), I've found them to be really good. They test kitchen those recipes to death.
As an example, on the Kraft website I clicked on their Taco Soup recipe. It uses nice round numbers so you don't have half a can of whatever left over. One drawback is it serves 12 1 cup servings (probably a 2 cup serving is a more realistic meal), but you can make some friends and share or get some Gladware and freeze them if you have access to a freezer. Don't forget to label the container with what it is and when it was made.
Crockpot.com also has recipes. When you're shopping for one, think SMALL. They are misleading and I can picture you ending up with a huge one because the box doesn't seem that big.
Good luck!
