Flavorful, easy, and versatile—that's the name of the game with this simple meatball recipe that highlights tender lamb and frozen spinach, which brings welcome moisture to the mixture. These are joined by a generous amount of salty pecorino Romano cheese, fresh mint for a ping of herbal balance, and spices to elevate the flavor profile. The result is a sophisticated meatball (yes, it's possible) that's perfect for tossing with pasta, dipping into a yogurt-based sauce, or piling onto soft bread for an easy sandwich. P.S. You could also use the mixture to make lamb burgers. Shape the mixture into 6 patties and grill or bake.
