4 tilipia fillets
1/2 cup mayo
1/4 cup grated parmesian cheese
1 tbs hot horseradish
Take a baking sheet, cover with foil, use cooking oil or other butter/oil for non-stick to the foil. Lay out fillets on the foil. Mix the other ingredients in a cup.
Cook fillets by broiler until nearly done. (depending on thickness and how close your fillets are too your heat source.) Roughly about 7-10 minutes. Pull out fillets and butter with sauce. Return to the broiler and cook till it just starts to turn brown.
Simple but good eating with easy clean up.
