How can I achieve the best results when grilling tilapia on a gas grill?

To achieve the best results when grilling tilapia on a gas grill, preheat the grill to medium-high heat, lightly oil the grill grates, season the tilapia with salt, pepper, and any desired herbs or spices, and grill for 3-4 minutes per side until the fish is opaque and easily flakes with a fork. Avoid overcooking to keep the fish moist and flavorful.
