1. Preheat your oven to 375°F. Line a baking sheet with parchment paper for easy cleanup.
2. In a large mixing bowl, combine ground beef, breadcrumbs, egg, garlic powder, onion powder, salt, and pepper. Mix until just combined, being careful not to overwork the meat.
3. Form the mixture into 1-inch meatballs and place them on the prepared baking sheet.
4. Bake the meatballs for 20-25 minutes, or until they are browned and cooked through.
5. While the meatballs are baking, heat olive oil in a large skillet over medium heat. Add pineapple chunks and cook for 2-3 minutes until they begin to caramelize.
6. Stir in sweet chili sauce and soy sauce, and bring to a gentle simmer. Allow the sauce to thicken slightly, about 3-4 minutes.
7. Once the meatballs are done, add them to the skillet, tossing to coat them thoroughly in the sweet chili pineapple sauce.
8. Let the meatballs simmer in the sauce for an additional 5 minutes, allowing all those delicious flavors to meld together.

This is where the magic happens! The sauce thickens, the pineapple sweetens, and your kitchen smells heavenly—just like those late dinners in my childhood home.
