I usually cut the recipe in half, which is easy for a math midget because it calls for two of everything. Also, the recipe calls for crushed tomatoes. I prefer diced for at least half of them. Don't forget that the usual 14-1/2 ounce size of canned tomatoes is half the size of a large can, so if you are making the full recipe, you'd need 4 cans of tomatoes.
2 cans pinto beans
2 cans black beans
2 cans kidney beans
2 large cans crushed or diced tomatoes
2 envelopes taco seasoning
Mix all ingredients together and simmer for a couple of hours. I usually use the Crockpot. One point per one cup serving!
