Preheat the oven to 400 degrees F. Prepare a large sheet pan or baking sheet with aluminum foil. Oil or spray with nonstick spray, then set aside.

Crack the egg into a small bowl or measuring cup. Measure all other ingredients and add to a large mixing bowl.

Using clean hands, combine all ingredients for the meatball mixture. Do not overwork. Shape into approximately ¾ oz. meatballs (about the size of a ping pong ball) and place ½-1" apart on the prepared baking sheet.

Bake for 20 minutes or until edges begin to brown and internal temperature safely reaches 165 degrees F. Remove from oven and allow to cool slightly.

Measure all ingredients for the sauce into a measuring cup. Whisk to combine, then set aside until meatballs are finished cooking.

To serve, add the cooked meatballs to a mixing bowl. Pour the prepared sauce over the meatballs, then use a spoon to carefully fold together until all meatballs are coated. Transfer to plates or bowls, if serving as an entree, or hold warm if serving as an appetizer.
