Not sure if this is Cuban and it uses canned beans and prepackaged seasoning, but my family thinks it’s real good.

2 tablespoons olive oil
1/2 cup chopped onions
1/4 cup chopped green peppers
2 cloves of minced garlic
1 (15 ounce) can Goya black beans (undrained)
3/4 cup water
1 teaspoon oregano
1/4 teaspoon sugar
1 package Goya sazon (without annato
1 tablespoon cider vinegar
2 cups cooked white rice (I use Basmati)
Heat oil in a medium sauce pan, saut� onion,green pepper, and garlic until tender.
Add remaining ingredients and stir until boiling, reduce heat and simmer until sauce is reduced – 15-20 minutes.
Sometimes I mash a few of the beans with the back of a spoon while it cooking for flavor and to thicken the sauce. Sometimes I add a can of chopped tomatoes.
Serve over rice.
