• 3 slices of sourdough bread
• 3 tbsps. tomato sauce (or ketchup or pizza sauce)
• 3 handfuls of Mozzarella chunks (or any other cheese suitable for pizza)

Instructions:
1. For a crispier base, toast the sourdough slices.
2. Spread tomato sauce on each slice, and top with cheese.
3. Bake in the toaster oven for 5-10 minutes until cheese melts.
