I am always looking for ways to get my son to eat, and black beans are a favorite. So I adapted this one from All Recipes. The original recipe called for one can of beans and one of corn, as well as two packages of 8-oz cheddar. We just topped ours with cheddar, and they were great!
1 pound ground beef
1 (1.25 ounce) package taco seasoning mix
2 (15 ounce) cans black beans, undrained
1 (6 ounce) can tomato paste
1 1/2 cups water
1/2 cup sour cream
Shredded cheddar cheese, for topping (can add some to stew too)
