Baked Fish Fillets

1 1/2 pounds grouper or other white fish fillets
Cooking spray
1 tablespoon fresh lime juice
1 tablespoon light mayonnaise
1/8 teaspoon onion powder
1/8 teaspoon black pepper
1/2 cup fresh breadcrumbs
1 1/2 tablespoons butter
2 tablespoons chopped fresh parsley

Preheat oven to 425°.

Place fish in an 11 x 7-inch baking dish coated with cooking spray. Combine lime juice, mayonnaise, onion powder, and pepper in a small bowl, and spread over fish. Sprinkle with breadcrumbs; drizzle with butter. Bake at 425° for 20 minutes or until fish flakes easily when tested with a fork. Sprinkle with parsley.

Notes: Haddock or cod would make good substitutes for the grouper. Adjust the baking time depending on the thickness of the fish.
