Another good one for getting rid of cans of beans
... a few more ingredients, but still pretty cheap.
Taco Soup
1 lb ground beef, browned and drained
1 can black beans, undrained
1 can pinto beans, undrained (original recipe calls for kidney, but I think it should be pinto)
1 can corn, drained
1 large (28 oz) can diced tomatoes, undrained (recipe calls for crushed, but whatever)
1 medium can sliced olives, drained (optional)
about half a small can chopped green chiles (optional)
1 packet taco seasoning mix
1 packet ranch dressing mix (I've never used it)
1 small onion, chopped (I use dehydrated, works fine)
Throw the whole lot into a large crock pot. Cook on low 4-6 hours.
Great with shredded cheese and sour cream on top, served with Jiffy corn muffins. Yum.
