Make the stuffing according to package directions (hard to make homemade stuffing when you are camping).
Clean trout by gutting only - leave the head and tail attached.
Lay out your tin foil (double thickness). Make sure it's enough to cover the trout completely when stuffed.
Lay the trout on the foil and squeeze lemon juice inside the cavity and season with salt and pepper to taste.
Fill with stuffing and drizzle 2 tablespoons of oil around the fish, wrap and seal tightly. Place on grill above open flame for approximately 45 minutes.
Remove from foil and unwrap. The skin will remove easily.
