1 can black beans- drained
1 can Kidney beans
1 can navy beans
1 can corn
1 can green chilies
1 32oz can diced tomatoes
1 pkg taco seasoning
1 pkg ranch dressing
1 lb ground beef- brown and drain
Only drain the black beans. Just dump everything in, heat and enjoy! It tastes best if you let it simmer for 40-ish minutes and let the beans break down a bit. If you want to make it even healthier and easier, use veggie/soy "ground meat" instead of the ground beef. Then you can just dump it in . . . no need to brown it first. Your kiddos definitely wouldn't notice the difference, but DH might a little (just the texture).
Sometimes I cook some whole grain macaroni noodles and serve it over that . . . it seems to go down easier for my kids.
It's absolutely best topped with freshly grated colby-jack cheese. Other good toppings are sour cream and chopped avocado.
