Southwestern Black Bean, Corn, Tomato, and Avocado Salad

My Sister-in-law asked for a recipe for a side to go with a Mexican dish and I looked through my recipes and found this one.  After I sent it to her, I thought it looked pretty good, so I  decided to make it for my lunches one week.  We both thought it was very good.  It is easy to make, and made enough for me to have lunch for 3 or 4 days.  I'll make this again either for lunch or as a side dish for Mexican food since I never seem to know what to serve with Mexican food!
