I make a Rice, Black Bean and Feta Salad, you could adapt it and use the salsa for the dressing.
1 can black beans, rinsed and drained
1 1/2 c. chopped tomatoes
1 1/2 c. cooked rice
1 pkg (4 oz) feta cheese
1/2 c. chopped celery
1/2 c. chopped green onions
2 tabl. choppedCilantro or parsley
1/2 c. Italian dressing
I didn't have any fresh tomatoes this week so I used frozen corn thawed. That would go well with salsa. Use the salsa for the dressing instead of the Italian. Take or leave out the feta.
