Cowboy Crack

A coworker brought this salsa/dip in to work one night and I was hooked! She wrote down the recipe for it and even though I've scoured the Internet looking for it so that I can give credit to the person/site it originated with I can't find this recipe exactly! Lots of variations out there so be adventurous if you like and add some chopped tomatoes or avocado, spice it up with hot peppers.

1 red pepper chopped
1 yellow pepper chopped
1 green pepper chopped
1/2 red onion chopped
1 can black beans drained and rinsed
1 can shoepeg corn drained and rinsed
1/2 c. vegetable oil
1/4 c. apple cider vinegar
1/4 c. sugar
cilantro to taste
1/4 to 1/2 cup feta cheese crumbles, to taste

Chop all the peppers and onions. In medium sized bowl mix together the peppers, onion, beans, and corn. In separate bowl mix together the oil, vinegar and sugar and pour over vegetable mixture. Stir well. Add cilantro, if desired, and feta cheese. Stir to mix. Keep refrigerated. Serve with tortilla chips.
