Combine flour, water, and yeast in a bowl and mix until a shaggy dough forms. Knead the dough on a floured surface for 5-7 minutes until smooth and elastic.

Place the dough in a lightly oiled bowl, cover, and let it rise in a warm place for 1-2 hours, or until doubled in size.

Preheat your oven to 475°F (245°C) with a pizza stone or baking sheet inside. Punch down the risen dough and roll it out into a 12-inch circle.

Carefully transfer the dough to parchment paper. Spread tomato sauce evenly over the dough, leaving a small border for the crust. Top with mozzarella cheese and pepperoni.

Slide the pizza with the parchment paper onto the hot pizza stone or baking sheet. Bake for 12-15 minutes, or until the crust is golden brown and the cheese is bubbly and slightly browned.

Remove the pizza from the oven, let it cool for a few minutes, then slice and serve immediately.
