Preheat oven to 325 degrees. In a large bowl, combine egg, parsley, tomato paste, garlic, milk, salt and pepper. Mix well with a wire whisk, making sure the tomato paste is completely dissolved. Add ground chicken, grated cheese and breadcrumbs. Use your hand to mix ingredients together. Mixture will be somewhat wet. Form medium size balls and place onto ungreased baking sheet or very large baking dish. Make the glaze by combining all the ingredients in a small bowl, then brush over meatballs. Bake for about 30 minutes or a little longer if needed.
