Step 1

Preheat the oven to 350 degrees.

Step 2

Spray the inside of a large baking dish with cooking spray. Place the fillets in the baking dish and cover with the pico de gallo and onion. Cover the baking dish tightly with aluminum foil and place in the oven.

Step 3

Cook for 35-45 minutes until the fish is done. (Cooking time will depend on how thick the fish fillets are. Fish is done when you can easily flake the fish with a fork.)

Step 4

Remove the foil and sprinkle the cotija cheese and cilantro on top of fish and tomatoes. Place back in the oven for 10 minutes until the cheese starts to melt a bit. Remove from the oven and serve immediately.
