oops, forgot the avocado.
Now it's perfect. I made bigger batch to take to a potluck. Tomorrow lunch I'm going to a restaurant, so I'm going to do something similar. I'll prepare ahead of time a bowl of black beans, mango, lime, cilantro, cumin, and will order a garden salad and dump my mixture on top. Then I'll probably be out of black beans though I'll still have some mango left. I wonder what I'll do for dinner.
