I found this recipe online while looking for a fresh, healthy, and fast way to prepare fish. If you prefer, you can bake the fillets in tinfoil packets with some little sauce on each one in the oven at 425*F for about 12 minutes
Rub trout fillets with soy sauce. Season with salt, pepper, and sugar; set aside.
Heat oil in a large skillet over medium-high heat. Add garlic, ginger, and green onions; cook and stir until golden brown. Add trout fillets and cook until browned and crispy, about 3 minutes. Turn fillets over, and continue cooking until the fish flakes easily with a fork, about 3 minutes more.
