Throw together bean salad

I had some left over black beans in the fridge that I wanted to use, but since my cook books are all still in boxes from the move and I was too lazy to get online, I just deicded to throw some things together. I started with the black beans and some diced white onions in the fridge. I cooked some frozen corn then strained it and ran it under cold water. I added that to the bead. Add a dash of olive oil and fresh lime juice (half a lime or so). Also add some salt, pepper, cayenne, and cumin. Mix and serve. I think this would be good with lots of other things so I suspect we will play around with this one.
