Meatball Parmigiana Sliders
(makes six sliders)
recipe adapted from Martha Stewart Living
1 slice of white bread, torn into 1-inch pieces
1/4 cup 2% milk
~.75 lbs ground beef
1 1/2 tablespoons finely grated Parmesan cheese
1/2 egg, beaten
1/4 teaspoon dried oregano
coarse salt
1/4 jar of marinara sauce
1/2 dozen slider rolls
2/3 cup coarsely grated mozzarella cheeseMake the meatballs: Soak bread in milk for 5 minutes. Gently mix bread and milk with meat, Parmesan cheese, oregano, egg, and 1/2 teaspoon salt. Refrigerate for at least 30 minutes.
Roll mixture into twenty-four 1-ounce balls (each about the size of a golf ball).
Heat sauce in a large heavy pot over medium heat. Drop meatballs into sauce, and bring to a gentle simmer. Cook, partially covered, until meatballs are cooked through, 20 to 25 minutes.
Make the sandwiches: Preheat oven to 400 degrees. Working in batches, arrange rolls, cut side up, on a baking sheet. Place 1 meatball, a spoonful of sauce, and 1 tablespoon mozzarella on bottom halves. Bake until cheese melts, about 3 minutes.
