How to Make It
In a small bowl, pour the milk over the bread and let stand until the milk is absorbed, about 10 minutes.
In a large bowl, gently mix the soaked bread with the ground meat, egg, cheese, parsley, salt, rosemary, oregano, paprika, garlic and cayenne until thoroughly combined. Form the mixture into 1 1/2-inch meatballs.
Preheat the broiler. Arrange the meatballs on a large rimmed baking sheet and brush them generously with olive oil. Broil about 4 inches from the heat for about 15 minutes, until nicely browned and firm. Transfer the meatballs to a serving platter and serve with the Spiced Tomato Jam.
