Mix all of the meatball ingredients in a small mixing bowl until combined evenly.
Roll 1 – 1 ½ inch meatballs and place them on the sheet tray with the veggies – they can rest right on top of the veggies or on the sheet tray.
Brush each meatball with the prepared teriyaki sauce, and then drizzle the rest of the sauce over the veggies on the sheet tray.
Bake at 425 degrees for 20 minutes.
