Easy Beans and Corn

I tried this recipe (found on the side of a can of black beans) for dinner tonight.  It was simple and delicious.

1 can black beans, drained
1 can sweet corn, drained
3 Tablespoons balsamic vinegar
2 green onions, chopped

Combine beans, corn, vinegar. 
Heat in microwave for 4 minutes. 
Sprinkle on green onions, stir so the onions wilt a bit. 
(I think 1/4 cup chopped red pepper would be nice to add as well for some color.)
