Preheat oven: Set oven to 180°C (350°F). Line a large baking tray with baking paper or lightly grease it.
Make the glaze: In a large bowl, combine the Lee Kum Kee Panda Brand Oyster Sauce, Lee Kum Kee Premium Soy Sauce, Lee Kum Kee Pure Sesame Oil, Lee Kum Kee Minced Garlic, and honey. Mix well until smooth.
Coat the ingredients: Add the deboned chicken marylands, quartered potatoes, capsicum, broccoli, and onion into the bowl with the glaze. Toss everything thoroughly so all ingredients are well coated.
Serve: Remove from the oven and let it rest for a few minutes. Serve straight from the tray for a simple family meal.
