Mix flour, salt, sugar, and yeast in a bowl.

Slowly add lukewarm water and mix to form a dough.

Knead the sticky dough for about 5 minutes until smooth.

Grease hands with oil and knead the dough on a flat surface.

Form the dough into a round ball, cover, and let it rest in a warm place for 90 minutes.

Prepare the pizza tomato sauce.

Generously oil a pan and dust with semolina.

In a mixing bowl, add oil, salt, tomatoes, pepper, and onions and mix well.

Punch the dough down and knead again for about half a minute.

Make 3 balls of equal size.

Oil your hands and flatten one ball, pulling it into a round shape and place it in the center of the pan.

Use your fingers to push through the edges and even out the pizza base.

Top the pizza base with pizza sauce, sprinkle with mozzarella cheese, arrange onions, bell peppers, and tomatoes, and top with more cheese.

Cook the pan pizza for 10-12 minutes or until done.
