Spray nonstick skillet with non-stick spray. Heat skillet to medium heat and add 1 tsp butter, mushrooms, and onion. Sauté until limp and onions are translucent. Add seasonings, and 1 Tablespoon of Madeira wine. Remove from heat and cool. Add parsley just before stuffing.

Wash and dry fish fillets. Spoon 1-2 Tablespoons of stuffing mixture onto the largest end of the fish fillet. Roll up from large end to small end. Secure with toothpick if needed. Place in small shallow baking dish. Melt butter and brush onto tops of fillets. Sprinkle breadcrumbs and lemon pepper seasoning over the top. Spray with butter flavored spray. Bake at 400º for 20–30 minutes until fish is flaky at its thickest part.
