You love the taste of fresh fish on the grill, but sometimes it sticks, especially when trying to flip, and is a mess to remove from the heat. Plus, you leave much of your dinner on the grates. Thinly slice enough lemon to support each fillet and place on the grill grates. Place your fish on top and grill as usual. The lemon slices are a natural barrier that allows the fish to cook without tearing apart. The citrusy flavor will enhance your recipe. It’s best to keep the grill lid closed during the cooking process.
