Preheat the oven to 400 degrees
In a large mixing bowl, combine the pork, lamb,
ground round, spinach, cheese, egg, basil, parsley,
garlic powder, salt, red pepper flakes, and 1/4 cup of
the bread crumbs. Using your hands, mix all ingredients
until well incorporated. Use immediately or place in
refrigerator for up to 24 hours.
Place the remaining 1/4 cup of bread crumbs into a
small bowl. Using a scale, weigh meatballs into
1.5-ounce portions and place on a sheet pan. Using your
hands, shape the meatballs into rounds, roll in the
bread crumbs and place the meatballs in individual,
miniature muffin tin cups. Bake for 20 minutes or until
golden and cooked through.
