Okay, here is the best way I've seen (so far) to prepare black beans.
Cook some onion, add some garlic, then add everything else: black beans (cooked, or canned), some honey, salt, pepper and a cup of beer. You can also add some cayenne or hot sauce or chiles or whatever you like for heat. Bring it to a bubble and just let it cook until the sauce has thickened. That's it. The beer gives it real depth, the honey just a bit of sweetness. I want some right now.
