2 lb. fish fillets (frozen or fresh)
2 tbsp. lemon juice
1/2 c. Parmesan cheese, grated
1/4 c. butter, softened
Dash hot sauce
3 tbsp. mayonnaise
3 tbsp. onions
1/4 tsp. salt

Thaw fish if frozen. Place fillets in a single layer on a well greased baking pan. Brush with lemon juice. Let stand for 10 minutes.

Combine remaining ingredients. Broil 4 inches from heat for 6 to 8 minutes. Remove from oven, spread with cheese mixture evenly over the fish and continue for 2 to 3 minutes until flaky.
