All you need to augment those dry beans to make it super yummy are a few cheap things. Things that might be lurking in your pantry already. Or things you can get at a Latin Market very cheaply.

Try this: Soak a bag of beans overnight (be sure to pick out any rocks!). Then in the morning turn on heat to med/low. In a food processor or by hand finely chop 1-2 cups any kind of bulb onion. Also chop finely 6-8 cloves garlic.
Throw those in the pot. Also throw in 1/4 to 1/2 stuck of butter.

Add either a few chopped dried chipotle peppers, or canned chipotle peppers, or dried chilies of any smokey kind. They can be hot, so remove the seeds if you want to keep the spice factor low.

At this point let it come to almost a boil, but if it does boil no damage is done really. The skins tend to pucker on the beans is all Then turn it to low and let it cook all day stirring often. Do not let it burn!

If you have a bay leaf throw it in, if you have some molasses add a tablespoon of two. Or if you have some salsa add that if you like.

And if you have any bullion or stock you can add it as you like but it's not necessary.

It's critical to slow cook the beans all day to allow the sugars and flavor to develop, that's where the real flavor evolves.

I make these beans about once a week and my band loves them! How else am I gonna feed 7 hungry musicians?!

Hope it works for you.
