I don't like sweet potatoes but this dish is pretty tasty.
2 cans black beans
1 can sweet potatoes [I used a can the same size as the beans...if you like sweet potatoes you could use the larger size can.]
1 can crushed pineapple [once again, I used the same size can as the beans...aprx.]
1 chopped onion
1-2 tsp. cumin
2-3 cloves of garlic
salt & pepper to taste
Saute onion and garlic in just a bit of butter. Add remaining ingredients. Stir. Simmer on low until hot all the way through.
Note: I had celery, so I sautéed some of that with the onion & garlic. Carrots would probably be good added as well.
