Meatball Calzone (Taste of Home)

My kids love meatball sandwiches, so I figured this calzone was just like a sandwich and yet soo easy to make. 

3 eggs, lightly beaten

1 cup seasoned bread crumbs

1 cup grated Parmesan cheese

3 teaspoons Italian seasoning

2 pounds ground beef

3 loaves (1 pound each) frozen bread dough, thawed

3 cups (12 ounces) shredded part-skim mozzarella cheese

1 egg white, lightly beaten

Additional Italian seasoning

1 jar (14 ounces) spaghetti sauce, warmed

In a large bowl, combine the eggs, bread crumbs, Parmesan cheese and Italian seasoning. Crumble beef over mixture and mix well. Shape into 1-in. balls.
 

Place meatballs on a rack in a shallow baking pan. Bake, uncovered, at 400° for 10-15 minutes or until no longer pink. Drain on paper towels. Reduce heat to 350°.
 

On a floured surface, roll each portion of dough into an 18-in. x 12-in. rectangle. Spoon a third of the meatballs and mozzarella cheese down the center of each rectangle. Fold dough over filling; press edges firmly to seal.
 

Place seam side down on greased baking sheets. Brush tops with egg white; sprinkle with Italian seasoning. Let stand for 15-30 minutes. Bake for 25-30 minutes or until golden brown. Serve with spaghetti sauce. Yield: 3 calzones (4 servings each)
