Heat oven to 375 degrees F. In a large bowl, combine ground pork, onion flakes, corn flakes, salt, pepper and egg.

In a small bowl stir together ketchup, brown sugar and dry mustard.

Spoon 2 tablespoons of the ketchup mixture into the pork and mix well.

Spray muffin tin with vegetable cooking spray. Form 6 meatballs and place in muffin tin.

Coat the top of each meatball with the remaining ketchup mixture.

Bake for 30 minutes at 375 degrees F., until nicely browned and glazed.
