Cook the Rice-Prepare your rice according to package instructions and set aside.
Preheat the Oven- Preheat oven to 425°F and line two sheet pans with parchment paper.
Make the Meatball Mixture- In a large bowl, combine ground chicken, garlic, green onions, almond flour, egg, salt, pepper, garlic powder, ginger, shredded carrots, and sesame seeds. Mix until just combined.
Form the Meatballs- Roll into 20–24 evenly sized meatballs and place on one sheet pan. Use a large cookie scoop to help.
Prepare the Broccoli- Spread broccoli on the second sheet pan. Spray with avocado oil and season with salt, pepper, and sesame seeds.
Bake- Bake both pans for 12–15 minutes until meatballs are cooked through and broccoli is tender with slightly crispy edges.
Add the Sauce- Drizzle teriyaki sauce over meatballs and broccoli. Return to oven for 3 minutes to warm the sauce.
Serve- Serve over rice and garnish with sesame seeds and red pepper flakes if desired.
