Italian Meatball Tartlets

"These Italian Meatball Tartlets are the perfect gameday appetizer! A couple of years ago, my mother-in-law taught me how to make one heck of a tasty Italian meatball. Those meatballs are good. Like really good. So I decided they needed to be on our appetizer menu. Since appetizers need to be handheld, I nestled those meatballs into flaky pieces of puff pastry. A spoonful of marinara sauce and a bit of mozzarella cheese finished these bad boys off. Appetizer deliciousness right there!"
