I mostly use them the ways you mentioned Cheryl. And, I have done the crockpot pre cook/freezing method that Alice mentioned as well.
I use a ton of black beans. We do burrito/rice bowls like you get at Chipotle, Q'doba and the like a lot. You can also use black beans to make refried beans, even though I mostly use pintos for that.
If I think of other ideas, I will send them along. Maybe do a google search or pinterest search for recipes using beans.
Hope you can make use of a good deal!
