i LOVE black beans too. i often do the refried. sautee a chopped clove of garlic and a 1/4 cup of chopped onion, then add the entire can of beans and mush to your liking.
also, i really enjoy a steaming bowl of BB soup.
sautee garlic and onion (green pepper/pablano if you like). Season with 1T of cumin and a little salt n pepper. Using 2 or 3 cans of beans, puree half of the bean mix in the blender. add all the beans into the pot with a cup of salsa (also to your liking - you can always add more). and cook on low until combined. i know this seems like a really general recipe without real quantities, but it's really hard to goof up. at times i also add corn and/or brown rice. you can easily garnish with green onions, cilantro, and plain yogurt. this is a very filling meal.
i also like to do BB patties, eaten as a burger substitute. plenty of recipes easily found on the net and extremely easy to put together too. I've used the BB burger recipe topped with some mashed potatoes for a veggie shepards pie.
