Black bean and mango salad

I am not a big meat eater so I am always looking for way of getting more protein into my diet. I love black beans so this seemed like a natural.  This is a simple salad that can be made ahead and kept in the refrig for a day or so. It's great for a picnic or as part of a buffet.

Ingredients:
2 c black beans, or 1 14 oz can
1 mango, diced into 1/2 pieces
1/2 small red onion, small dice
Juice and zest of one lime
1/2 cilantro, chopped

Rinse and drain the beans. Put them into a bowl, add the rest of the ingredients and toss.  Chill for at least 30 minutes or longer if desired.  The flavors will marry as it sits and become more complex.

Easy peasy. Enjoy!
