Directions: To make stuffing, melt butter in a frying pan, add onion and cook for 5 minutes or until transparent. Place apple and breadcrumbs in a bowl, add onion, lemon juice, mint, parsley and black pepper to taste and mix to combine.
Fill cavity of each trout with stuffing. Secure openings with toothpicks and lightly brush outside of each trout with oil. Cook trout on a preheated medium barbecue for 5-8 minutes on each side, or until flesh flakes when tested with a fork.
