01 - Preheat oven to 400°F (200°C) and line a baking sheet with parchment paper.
02 - Place bagel halves cut side up on the prepared baking sheet.
03 - Spread approximately 2 teaspoons pizza sauce over each bagel half.
04 - Sprinkle a thin layer of shredded mozzarella cheese over the sauce.
05 - Cut mozzarella slices into thin strips. Arrange strips across each bagel half, overlapping to mimic mummy bandages and leaving spaces for the eyes.
06 - Position two olive slices at the top of each bagel half to create eyes.
07 - Bake in the preheated oven for 10 to 12 minutes or until cheese is melted and bubbly.
08 - Allow to cool for one minute before serving.
