Season trout with salt and pepper. Mix
together rosemary, oregano, olive oil and garlic in a small
bowl. Gently open fish and spread herb mixture evenly across
flesh. Lay 3 slices of lemon on one side of each fish and
close.
Lightly oil grill. Cook fish 4 minutes
per side, or until skin is crisp and blackened and flesh is
opaque and flakes easily with a fork. Serve immediately.
