I love Cuban black beans, but preparing them from scratch is time-consuming. Here's a recipe that gives you perfectly acceptable results in 15 minutes. 2-15 oz cans of seasoned black beans 1/4 c diced onion 1/4 c diced green bell pepper 1 clove garlic, minced 2 tsp olive oil 1 tsp ground cumin 1/2 tsp black pepper In a saucepan, sauté the onion, pepper, and garlic in  the oil until soft, about 5 minutes. Stir in the cumin and pepper and, a minute later, the beans (with their liquid). Cover and simmer for 5-10 minutes. Serve over white rice.
