3/4cuppanko breadcrumbsgluten free panko will work fine
1/4cupfinely minced onion
zest of 1 small lemonabout 1 teaspoon
3/4cupshredded Pecorino Romano or Parmesan cheese
1/2teaspoonfreshly ground black pepper
1quartFive Minute Marinara Sauce
Preheat the oven to 400 degrees, setting the rack in the upper third of the oven. In a large bowl, combine everything except the marinara and the mozzarella. Lightly mix together, using your hands or a large spoon. Scoop and shape into small meatballs and place on a foil lined baking sheet. Place the meatballs fairly close together on the tray to make them fit. Spoon about a half tablespoon of sauce over each meatball. Bake for 15 minutes.
Remove meatballs from the oven and increase the oven temperature to broil. Spoon an additional half tablespoon of sauce over each meatball and top with a small square of mozzarella. (I cut the thin slices into pieces about 1" square.) Broil an additional 3 minutes, until the cheese has melted and turned golden. Serve with additional sauce. Enjoy!
I'd never bought ground chicken before, but it turned out to be very easy to find in the meat department with all the other kinds of chicken.
