Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
In a large mixing bowl, combine the ground chicken, panko breadcrumbs, green onion, minced garlic, grated ginger, soy sauce, and sesame oil. Mix until just combined; be careful not to overmix.
Scoop out about 1 inch of the mixture and roll into balls, placing them on the prepared baking sheet. You should have approximately 20 meatballs.
Bake the meatballs in the preheated oven for 18-20 minutes or until cooked through and golden brown on the outside.
In a small saucepan, combine the honey, rice vinegar, and teriyaki sauce. Heat over medium-low until warmed and slightly thickened, stirring occasionally.
In serving bowls, place a generous scoop of cooked jasmine rice. Top with the baked chicken meatballs, steamed broccoli florets, and drizzle the warm teriyaki sauce over the top.
Sprinkle sesame seeds and additional green onions over each bowl for garnish. Serve immediately while warm.
