In a large mixing bowl, combine ground chicken, breadcrumbs, chopped green onions, grated carrot, minced garlic, minced ginger, beaten egg, salt, and pepper. Mix until well combined.
Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
With your hands, form the meat mixture into small meatballs, about 1 inch in diameter, and arrange them on the baking sheet.
Bake the meatballs in the preheated oven for about 15-20 minutes, or until they are cooked through and browned on the outside.
While the meatballs are baking, heat sesame oil in a sauté pan over medium heat. Add the pineapple chunks and sauté for about 3-4 minutes until they are caramelized slightly.
Pour the teriyaki sauce over the pineapple in the sauté pan and stir to combine. Allow the sauce to simmer for a couple of minutes until it thickens slightly.
Once the meatballs are done baking, carefully add them to the sauté pan with the teriyaki pineapple sauce. Gently stir to coat the meatballs evenly in the sauce and pineapple.
Cook for an additional 2-3 minutes on low heat to allow the flavors to meld.
Remove from heat and serve immediately.
Notes
Serve over steamed rice or quinoa, and garnish with sesame seeds and extra green onions.
