Take 4 Tilapia fillets ( fresh or frozen), place in the center of a 12 x18 sheet of reynolds wrap aluminum foil.
Slice onions & peppers and place on top of fillets. Sprinkle with fresh or dried rosemary, drizzle honey & lemon over top and place 1 ice cube on top. Bring sides of foil up to meet in the middle and fold down, roll ends to seal.
Bake at 350 degrees for 12-15 minutes, depending on how thick the fillets are. The ice cube will cause steam to help keep the fish or chicken tender. Be careful when removing from oven, I always place a cookie sheet under as I pull it from the oven.
You can also do this with chicken and replace the lemon with orange. Enjoy.
