To make the meatballs. Combine the meat, 1 tablespoon tamari/soy sauce, 1 tablespoon ginger, green onions, and a pinch of pepper in a bowl. Mix until just combined. Coat your hands with oil, and roll the meat into tablespoon-size balls. The mix will be wet. Place 2 tablespoons cornstarch in a shallow bowl. Dredge the meatballs in cornstarch to coat. Take the remaining 1 tablespoon cornstarch and mix with 2 tablespoons water, set aside.To make the sauce. In a glass jar, whisk together 1/2 cup tamari/soy sauce, 1/4 cup honey, and 1/3 cup water. Heat the oil in a large skillet over medium heat. Add the meatballs, cook until seared all around, about 8 minutes. Remove the meatballs from the skillet.To the skillet, add the broccoli and cook until lightly charring, 5 minutes. Add the garlic, ginger, and chili flakes, cook 1-2 minutes. Pour in the tamari/honey sauce. Bring to a boil, boil 3-4 minutes, then add the chicken. Toss with the sauce and cook until the sauce starts to thicken. Pour in the cornstarch slurry and cook another 2-3 minutes, until the sauce coats the meatballs.Serve the meatballs and sauce over steamed rice with sesame seeds, green onions, and dipping sauce (recipe in notes).
