Boil 'em, mash 'em, stick 'em in a stew.

But actually though. Spicy Red beans and rice is delicious, black bean burgers, anything with chick peas like hummus wraps or chick pea fritters, vegetable tacos and burritos with black beans... there are loads of things.

I very much like red beans and rice when it's particularly spicy. Can add some sausage for heartiness too

Tomato soup with kidney beans can make it way more filling and gives the taste more body. Other less-western combinations with tomato work as well; like rice / beans, some sweet pepper, onion / tomato mixed sauce (perhaps even add apple or banana).

Otherwise stuff like Burritos and Chili recipes are always great.
