Mix all the pizza sauce ingredients in a bowl until it's homogeneous then set aside.
To make pizza dough, mix the flour, salt and yeast then add water and knead them well. Rest the dough for about 2 hours in an oiled and covered bowl.
After 2 hours, dust the bench which you will roll out the dough with flour. Divide the dough in half. Then divide each piece into five small pieces. Roll the small pieces into the balls.
Press the balls with your hands and expand it by gently pulling on the edges and continue to rotate it. You will get 3 mm thick discs.
Deep fry the discs in a medium pot with vegetable oil at 180°C/355°F, until each side turns golden. When it is fried, it will turn into low dome-shaped discs. Place these discs on a baking tray lined with waxed paper. Press in the middle to get little dents.
Put 1 tablespoon of pizza sauce in the dent of each disk.
Scatter the mozzarella cheese on pizza sauce. Place the fresh basil leaves on mozzarella cheeses. Sprinkle the parmesan cheese on top.
Bake until the cheeses completely melted for about 10 minutes at 190°C/375°F preheated oven.
After the mini montanara pizzas are baked, remove the baking tray from the oven, drizzle the olive oil on top.
Serve slightly warm.
