Arrange the pepperoni slices in a single layer in the skillet. Scatter 1/4 cup of the mozzarella over the pepperoni and cook for about 30 seconds, until the cheese starts to melt.

Place the tortilla over the melting cheese and pepperoni. Press gently with a spatula so the cheese sticks to the tortilla.

Add the remaining 1/2 cup mozzarella over the sauced half. Fold the plain half over the filling and press gently.

Cook for 1-2 minutes per side, flipping as needed, until the tortilla is golden and the cheese is fully melted. Rest for 1 minute, then slice into wedges and serve with warm sauce.
