Preheat oven to 350F. In large bowl, knead together all meatloaf ingredients, except teriyaki sauce, with your hands. Spray 9-inch-by-5-inch loaf pan with vegetable oil spray. Pack the meatloaf into the loaf pan. Bake for 1 hour. Let rest 5 minutes before inverting the pan to transfer the meatloaf to a cutting board. Slice the meatloaf and arrange the slices on a serving platter. Pass teriyaki sauce separately or drizzle over slices to serve.
