Making Hawaiian Meatballs is a straightforward process. Just follow these steps:

1. Preheat the Oven: Set your oven to 400°F (200°C) and line a baking sheet with parchment paper.
2. Mix the Ingredients: In a large mixing bowl, combine ground beef, breadcrumbs, pineapple tidbits, green onions, minced garlic, soy sauce, teriyaki sauce, egg, black pepper, and salt until well blended.
3. Form the Meatballs: Shape the mixture into 1-inch meatballs and place them on the prepared baking sheet.
4. Bake: Cook in the preheated oven for 20-25 minutes or until the meatballs are browned and cooked through.
5. Prepare the Sauce: While the meatballs bake, prepare the glaze by mixing ketchup, brown sugar, teriyaki sauce, and rice vinegar in a saucepan over medium heat. Stir until the sugar dissolves and the mixture is smooth.
6. Add Vegetables: Mix in the diced bell peppers and pineapple tidbits. Allow the sauce to simmer for about 5-10 minutes.
7. Glaze the Meatballs: Once the meatballs are done baking, gently toss them in the glaze until well coated.
8. Serve: Remove from the oven and transfer the glazed meatballs to a serving dish. Sprinkle with sesame seeds for decoration.

These simple steps ensure that your Hawaiian Meatballs will turn out amazing every time.
