You can easily make a few batches of garlic parmesan meatballs at once and freeze them for easy dinners. Allow the chicken parm meatballs to come to room temperature, then flash freeze them on a lined baking sheet. Transfer to a freezer bag (so you can grab as many as you need at a time) and store for up to 3 months. To reheat, thaw in the refrigerator and cook for about 10 minutes in a 350°F oven.
