In a small bowl, dissolve the yeast and sugar in warm water. Let it sit for 5 minutes until frothy. In a large mixing bowl, combine flour and salt. Add the yeast mixture and olive oil, mixing until a dough forms. Knead the dough on a floured surface for about 10 minutes until smooth. Place in a lightly oiled bowl, cover, and let rise for 1 hour.

In a saucepan, combine crushed tomatoes, garlic, oregano, and basil. Simmer over medium heat for 15 minutes, stirring occasionally. Season with salt and pepper to taste, then set aside.

After the dough has risen, punch it down and roll it out onto a pizza stone or baking sheet. Ensure the dough is evenly spread with a slight border for the crust.

Spread a layer of pizza sauce over the dough, leaving the border untouched. Sprinkle mozzarella cheese evenly over the sauce, then add pepperoni and bell peppers as desired.

Preheat your oven to 475°F (245°C) to ensure it reaches the right temperature before baking the pizza.

Place the pizza in the preheated oven and bake for 12-15 minutes. The pizza is done when the crust is golden and the cheese is bubbly and slightly browned.

Allow the pizza to cool slightly before slicing. Serve each slice with your choice of sides or enjoy it on its own!

Store any leftover pizza in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave before serving.
