Just had this for lunch. Excellent!
I will list my measurements (for 1 serving), but feel free to alter.

3/4 yellow corn (Trader Joe's canned is excellent!)
1/2 cup black beans (rinsed)
chopped red onion (about an 1/8 of onion)
chopped red bell pepper (about n 1/8 of pepper)
2 TBLS salsa (fresh)
red wine vinegar
seasoned with:
cumin
chili powder
garlic powder
salt.

Enjoy

I just fixed this for dinner. With a few modifications. It is great. This will definitely become part of my eating program.
