Place a whole trout on a large sheet of aluminum foil. Drizzle the top and inside with half of the olive oil. Sprinkle it with salt and pepper on the outside and inside until evenly coated.
Insert fresh herbs and lemon slices into the cavity. Tightly wrap in foil to seal well. Repeat for the remaining fish.
Place both wrapped trout on a baking sheet and place on the middle rack in the oven. Bake for 12-16 minutes, or until the internal temp reaches at least 145° F and the fish flakes easily with a fork.
Serve immedialty drizzled with the fresh squeeze lemon slices.
