PREHEAT oven to 400°F. Line a 13x9x2-inch baking pan with Reynolds Wrap® Non-Stick Foil with non-stick (dull) side toward food.
PLACE tilapia in foil-lined pan.
MIX lime juice, olive oil, seafood seasoning, garlic, salt and red pepper flakes in a medium bowl until well blended. Pour over fish.
BAKE 18 to 20 minutes or until fish flakes easily with fork. Serve 1/2 fillet in each tortilla with lettuce, salsa and avocado.
Fish can also be grilled on a sheet of Reynolds Wrap® Non-Stick Foil. Place foil with non-stick (dull) side up on grill grate. Use a grilling fork to punch holes in foil for drainage. Grill 5 to 10 minutes, or until fish is opaque and flakes easily when tested with a fork.
