cuban food is influenced by Spanish, French, African, Arabic, Chinese, and Portuguese cultures.
the most important ingredient involved in cuban cooking is the sofrito(onion, green pepper, garlic, oregano, and ground pepper quick-fried in olive oil.)The sofrito is what gives the food its flavor.
now that being said, i have a great black bean soup that is probably what you are looking for..
it ends up like red beans and rice in texture..think bean gravy..lol
3/4 lb. black beans
1 1/2 qt. cold water
2 oz. salt pork (optional)
