I'm on a diet and always looking at high fiber food that's high in nutrients and easy on the calories.
The small dried black beans soften up easily with soaking and cooking and after reading about Cuban style food I decided to cook them with rice. I've found it's better to cook and drain the beans first then add them to the rice dish which I usually make with stir fry type veggies and either chicken or fish.
Spices are optional, I either go Thai or Indian Curry or even Mexican by adding tomatoes and jalapenos. I'm not afraid to use packet stuff if I'm feeling idle. (Rephrase that to "more idle than usual").
The result is tasty, filling and you crap like an elephant the next day.
