To prepare a thin crusted focaccia pizza with fresh tomato basil and mozzarella recipe, first you need to prepare the dough. Preheat the oven to 450 degrees Fahrenheit (230 degrees Celsius). Lightly grease two baking sheets with non-stick cooking spray. Place the flour, salt, and pepper into the mixing bowl. Add the butter and mix until the mixture resembles coarse crumbs. Mix in the melted butter with the yeast and water. Cover the bowl with cling wrap and let rise until doubled in size, about 1 hour. Bake the pizza for 20 to 25 minutes or until browned. Remove from oven and allow to cool before slicing.
