Black beans are great. Goya is a good brand to buy if you don't have the time or money to cook them yourself . They sell the large 1lb can for about $1.50
I usually:
* Blend a 1lb can of black beans in blender
* Sautee some garlic and onion in a pan with a little OO
* Pour the blended black beans into pan
* Add a dash of cumin as soon as I see bubbles
* Stir for a few minutes
* Remove from heat
Eat with some grilled or broiled chicken, brown rice, avocado, and sprinkle some queso fresco on the beans.
You can also make tostadas - my favorite! Spread the blended black beans on a tostada, add some shredded chicken, monterrey or queso fresco, shredded cabbage or lettuce, diced tomatoes, and your favorite hot sauce - home made beats all
... hmmm, I think I'll fix tostadas for dinner tonight, haven't had them in a while
