Preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper for the broccoli.
In a medium bowl, combine the lean ground turkey, minced garlic, grated ginger, low sodium soy sauce, honey, and rice vinegar. Mix until just combined, taking care not to overwork the meat.
Form the mixture into small meatballs, about 1 inch in diameter.
Heat a non-stick skillet over medium heat and lightly sear the meatballs on all sides until browned, about 3-4 minutes per side.
Transfer the seared meatballs to a small saucepan, pour any remaining sauce in the pan over the meatballs, and let them simmer on low heat for about 5-7 minutes to finish cooking and absorb the sticky teriyaki glaze.
Meanwhile, toss the broccoli florets with a light drizzle of olive oil (optional, if within macro goals) and a pinch of salt, then spread evenly on the prepared baking sheet. Roast in the preheated oven for 12-15 minutes until tender and slightly charred.
Warm the cooked brown rice if needed, or serve it fresh alongside the meatballs and roasted broccoli.
Plate the meatballs over or beside the brown rice and add the roasted broccoli on the side. Drizzle any extra teriyaki sauce from the pan over the dish and serve hot.
