Instructions

  1. Step 1: Pat trout fillets dry with paper towels. Brush both sides with 2 tablespoons olive oil, then season with 1/4 teaspoon salt and 1/4 teaspoon black pepper.
  2. Step 2: Slice 1 lemon into thin rounds and place 2 slices on each fillet. Tuck 2 tablespoons fresh thyme leaves between the lemon slices and fish.
  3. Step 3: Preheat grill to medium-high (375°F/190°C). Grill fish for 4-5 minutes per side, until the flesh is opaque and flakes easily with a fork.
