Preheat the oven to 375℉.
Chop the onion. In a large bowl, mix the onion, egg, oats, milk, seasonings, and cheese.
1 small onion (finely chopped), 1 large egg, 1/2 c. quick oats, 3/4 c. milk, 1 1/2 tsp. salt, 1 tsp. black pepper, 1 tsp. garlic powder, 2 - 2 1/2 c. shredded cheddar cheese
Add the meat and mix only to combine. (Overmixing produces tough meatloaf.)
2 lb. ground beef (I prefer 85/15)
Divide the meat into eight portions, and shape each portion into a small loaf.
Place the loaves, with a bit of space between each one, on a large greased baking tray with sides. (For easier cleanup, line the tray with parchment or foil sprayed with cooking spray.)
Divide the glaze between the loaves and spread over the tops.
Bake, uncovered, for about 35 - 40 minutes or until cooked through. (at least 160° internal temperature)
