In a large bowl, combine the eggs, milk, bread crumbs, cheese, and onion.

Crumble sausages over the mixture and mix well.

With wet hands, shape the mixture into 1-inch balls.

Place meatballs on a greased rack in a shallow baking pan.

Bake, uncovered, at 400°F (200°C) for 15-20 minutes, or until a thermometer reads 160°F (71°C).

Drain meatballs onto paper towels.

Meanwhile, in a large skillet, whisk together the chili sauce, maple syrup, Worcestershire sauce, and maple flavoring until smooth.

Bring the sauce to a boil.

Cook and stir for 1-2 minutes, or until thickened.

Add the meatballs to the sauce; stir to coat.
