Baked Snapper with Onions, Peppers, Capers, and Feta

2 medium-sized Snapper filets
1/2 tablespoon olive oil
1/2 cup diced red bell pepper
1/4 cup diced red onion
2 tablespoons diced capers
1/3 cup crumbled fat free feta cheese
1-2 tablespoons light mayo

Preheat oven to 425 F. Spray baking sheet with cooking spray.

Heat olive oil in a frying pan and sauté red pepper and onion about 3 minutes. Add capers and sauté about 2 minutes more. Turn off heat.

Put fish on the baking sheet and season with salt and pepper. Spread a small amount of mayo evenly over the surface of each piece of fish. Stir feta into red pepper/onion/caper mixture and spread that over the top of fish.

Bake until fish is opaque and white throughout and topping is starting to brown, 10-15 minutes, or longer depending on the thickness of the fish.
