Preheat the oven to 375°F (190°C).

Line the baking sheet with parchment paper.

Lightly flour your work surface and roll out the bread dough into a rectangle.

Spread marinara sauce evenly over the dough and sprinkle shredded mozzarella and pepperoni slices.

Slice the dough into squares or strips using a sharp knife or pizza cutter.

Stack the cut pieces vertically in the prepared baking sheet.

Brush with olive oil and sprinkle garlic powder and Italian seasoning.

Bake in the preheated oven for 25 minutes or until golden brown and bubbly.

Let the bread cool for a few minutes before serving.
