Preheat your oven to 400°F (200°C) to ensure a perfectly crispy tortilla.
Place your large flour tortilla on a baking sheet. Consider lining it with parchment paper to prevent sticking.
Spread a generous layer of marinara sauce over the tortilla, leaving a small border for crust.
Sprinkle a generous amount of mozzarella cheese over the sauce, covering the entire surface.
Add your choice of additional toppings and get creative!
Bake for about 10-12 minutes, until the cheese is melted and the edges are golden brown.
Remove from the oven, let cool for a minute, slice, and serve hot!
