Melt butter in microwave. To the crushed crakers, add the salt,pepper,and Italian seasoning. Roll fish fillets in butter then press into cracker mixture on both sides. Line a cookie sheet with aluminium foil coated with cooking spray. Lay fillets on cooking sheet and drizzle remaining butter on top. Sprinkle fresh grated parmesan cheese over the tops of each fillet. Can find fresh grated already in a package at Walmart or any grocery store. Bake at 350 for about 15 to 20 minutes or until fish flakes easily.
