PREHEAT OVEN: Preheat the oven to 400 degrees Fahrenheit
PREPARE BAGELS: Cut bagel in half and brush with olive oil and place on a baking sheet. Sprinkle each with a little flakey sea salt. Bake cut side up for 4-6 minutes until lightly crisp and golden brown on the bottom.
PREPARE TOPPINGS: While the bagels bake, prepare the toppings: grate mozzarella cheese and chop basil.
FIRST TOPPINGS: Remove the tray from the oven. Top each bagel half with about 2 tablespoons pizza sauce and 3 to 4 tablespoons shredded mozzarella cheese.
FINAL BAKE: Bake the bagels 6 to 7 minutes until the cheese is melted. Top with fresh basil, a drizzle of olive oil, and enjoy!
