Preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper.
In a large mixing bowl, combine the ground chicken (or turkey), breadcrumbs, sliced green onions, egg, minced garlic, grated ginger, and a pinch of salt and pepper. Mix until well incorporated.
Using your hands, shape the mixture into 1.5-inch meatballs, placing them on the prepared baking sheet.
Bake the meatballs in the preheated oven for 20-25 minutes, or until they’re golden brown and cooked through.
While the meatballs are baking, prepare the teriyaki sauce: In a small saucepan, combine soy sauce, brown sugar, and sesame oil. Heat over medium-low heat, stirring until the sugar dissolves. Allow to simmer for a few minutes until the sauce thickens slightly.
In a separate pot, steam the broccoli florets for about 5-7 minutes until tender and bright green.
Place a portion of cooked rice in each bowl. Top with 3-4 meatballs, steamed broccoli, and a handful of shredded carrots.
Drizzle the teriyaki sauce over the top of each bowl.
Garnish with sesame seeds and additional green onions.
