Instructions
Preheat the broiler and set an oven rack on the second-highest rack. Line a baking sheet with heavy duty aluminum foil and grease with the olive oil.
In a bowl large enough to hold all of the ingredients, beat the egg. Add the chopped spinach, scallions, and garlic and stir until evenly combined. Add the ground turkey, turkey sausage, mozzarella, Parmigiano-Reggiano and breadcrumbs. Using your hands, mix until evenly combined. Shape the mixture into 1-1/2 inch balls and place on the prepared baking sheet.
Broil the meatballs until golden brown on top, about 10 minutes.
Meanwhile, heat the tomato sauce in a large pan on the stovetop. Add the broiled meatballs and simmer over low heat for 5 to 10 minutes, or until the meatballs are fully cooked.
Freezer-Friendly Instructions: These can be frozen in their sauce for up to 3 months. When ready to serve, reheat the meatballs in their sauce on the stovetop over medium heat until hot in the center.
