• Preheat oven to 400 degrees Fahrenheit and spray a 9x13-inch baking pan with nonstick cooking spray.
• To a large bowl add the 2 pounds lean ground beef, ⅔ cup panko bread crumbs, 2 tablespoon dry minced onion, 1 large egg, ¼ cup milk, 1 ½ teaspoons ground ginger, 2 teaspoons salt, and ¼ teaspoon ground black pepper. Mix well to combine.
• Scoop the meat mixture out into 1 ½ tablespoon pieces and roll into balls, place them in the prepared baking dish. Bake uncovered for 20-25 minutes until the meatballs are cooked through.

Teriyaki Sauce

• In a medium saucepan, add the 1 ½ cup cold water, ¾ cup packed light brown sugar, ½ cup low-sodium soy sauce, 1 teaspoon garlic powder, 3 tablespoons cornstarch, and 1 teaspoon sesame oil.
• Whisk the sauce ingredients together and cook over medium heat, whisking occasionally until it thickens and no lumps remain.
• When meatballs are done baking, coat them in the teriyaki sauce and serve over cooked rice.
