In a large bowl, combine warm water, sugar, and yeast. Let it sit for 5 minutes until frothy.
Add olive oil and salt to the yeast mixture.
Gradually mix in the flour until a dough forms.
Knead the dough on a floured surface for about 5-7 minutes.
Place the dough in a greased bowl, cover, and let it rise in a warm place for 1 hour.
Preheat the oven to 400°F (200°C).
Roll out the dough into a rectangle on a floured surface.
Spread pizza sauce evenly over the dough.
Sprinkle mozzarella cheese and arrange pepperoni slices on top.
Roll the dough tightly and place it seam-side down on a baking sheet.
Bake for 25-30 minutes or until golden brown. Let it cool slightly before slicing.
