How to Reheat: Add the desired amount of kielbasa and onions to a small frying pan over low heat and cook until hot. You can also heat in a microwave-safe bowl. Top with the desired cheese and heat until melted.
How to Freeze: Keep the cooked meat and onions separate from the buns and sauce and cover in the freezer for up to 2 months. Thaw for 1 day in the refrigerator before reheating.
