Preheat grill on high. Whisk lemon juice, olive oil, oregano, red pepper flakes, 1 Tbsp salt, 1 tsp pepper together in a small bowl. Set aside.
Pre-oil the grill with vegetable oil to prevent sticking. Season fish with salt and pepper and cook over medium high heat for 2-3 minutes per side. Remove fish to a flat platter and perforate with a fork. Pour sauce over fish, while still hot. Cover with tin foil to rest 5 minutes.
