Top each biscuit with 1 heaping tablespoon (or a large pinch) of shredded mozzarella cheese, 2 tablespoons of prepared mac 'n cheese, ¼ tsp Italian seasoned bread crumbs and a dash of pepper.
Gather the edges of the biscuit around the mac 'n cheese to make a bundle. Pinch to seal.
Put bundles in a greased 9×13 inch pan spaced apart, sides not touching.
Brush the tops with a beaten egg white and sprinkle with grated Parmesan cheese.
Bake at 350°F for about 30 minutes or until golden brown.
