Cut the pineapple, bell peppers, and onion into 1 1/2 - 2 inch pieces.
In a large mixing bowl, combine the Ground Beef, breadcrumbs, eggs, soy sauce, and spices. Mix well.
Use your hands to form meatballs, using about 3 Tablespoons of the mixture at a time.
Make the kabobs by alternating meatballs, peppers, onions, and pineapple on wooden or metal skewers.
Brush the grill grates with olive oil to prevent sticking. Grill over medium heat with the lid down for a total of 15 minutes, turning at least once.
While kabobs are grilling, combine the sauce ingredients in a small saucepan and whisk well. Bring the mixture to a boil, then reduce heat and stir until thickened (about 2 minutes).
Brush sauce generously over kabobs; remove from grill.
Serve with remaining sauce for dipping.
