Natalie'S Specialty Fish
["1 lb. frozen haddock, cod or perch", "4 Tbsp. Hellmann's mayonnaise", "2 tsp. lemon juice", "1 onion, cut up very fine", "1/2 c. grated Parmesan cheese"]
["Let fish defrost (block) just long enough so that you can cut it into 4 or 5 pieces.", "Place in casserole with enough oil on the bottom of the casserole to keep from sticking at 400\u00b0", "for about 15 to 20 minutes."]
