Rinse tilapia fillets under cool water, and pat dry with paper towels. Place fillets in baking dish. Pour lemon juice over fillets, then drizzle butter on top. Sprinkle with garlic, parsley, and pepper. Bake in preheated oven until the fish is white and flakes when pulled apart with a fork, about 30 minutes.
Let the fish sit at room temperature while the grill heats; cold fish tends to stick. Oil and season the tilapia to taste and lay it on the hot side of the grill. Grill tilapia fillets for 2 to 3 minutes and turn them over. Cook for an additional 2 to 3 minutes, or until the fillets pull away cleanly from the grill. To grill whole tilapia, place it on the grill and cook it for 4 to 5 minutes on each side.
