- Mix in chopped mushrooms or spinach for extra veggies.
- Use part-skim mozzarella to reduce fat content without sacrificing flavor.
Storage
Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, warm in the oven at 350°F (175°C) for about 15 minutes or until heated through to keep the cheese melty and delicious.
