Preheat your oven to 500 degrees F or as hot as it can go.
On a floured surface, shape pizza dough into a 12” round or rectangle. Transfer to a large baking stone or baking sheet.
Quarter each tomato and gently squeeze wedges over sink to remove the excess juices and seeds. Add to the bowl of a food processor or blender, along with garlic and half of the basil. Process until tomatoes break down into a sauce, scraping down sides as needed. If desired, strain to make a thicker sauce. Evenly spread sauce over pizza dough and top with mozzarella slices, leaving some space between pieces of mozzarella.
Bake for 5-10 minutes—exact cooking time will vary depending on your oven temperature. The crust should be golden brown and the cheese bubbling.
Sprinkle pizza with basil and let cool briefly before slicing and serving.
