#552: Meatball Calzones

I had this recipe for calzones so I decide to make these slightly healthier by using ground chicken.  We all enjoyed these immensely and plan to make these again soon.  They are so easy to make!!  Sorry, I should have cut this open so you could see the inside.

8 ounces ground beef

1/2 small onion, finely chopped (about 1/4 cup)

2 cloves garlic, minced
1 teaspoon Italian seasoning

1/3 cup fresh bread crumbs

1/2 teaspoon salt

1/2 teaspoon pepper

1/2 cup tomato sauce

1 1-lb. piece pizza dough, defrosted if frozen

1/2 cup shredded mozzarella

1 large egg

Preheat oven to 400°F; line a rimmed baking sheet with foil. In a bowl, mix beef, onion, garlic, Italian seasoning, bread crumbs, salt and pepper until well combined. Shape mixture into 16 1-inch balls and place on baking sheet. Bake for 12 to 15 minutes, turning often. Place tomato sauce in a large bowl. Toss meatballs with sauce and set aside to cool.

Reduce oven temperature to 375°F. Line a baking sheet with foil and mist with cooking spray. Divide dough into 4 pieces. Roll each piece into a 7- to 8-inch circle. Divide meatballs among dough circles, placing them on bottom halves and leaving a 1-inch border. Sprinkle each calzone with cheese. Fold dough over filling and roll bottom edge over top, pressing and crimping together to seal. Beat egg with 1 Tbsp. water and brush all over calzones. Make a slit in top of each calzone to let steam escape. Place calzones on baking sheet and bake until golden brown, about 40 minutes. Let rest for 5 minutes before serving.
