To prepare the sauce, heat the olive oil in a large skillet over medium-high heat. Add in the onion and garlic and cook until tender and fragrant, about 5 minutes.

Add in all remaining sauce ingredients, bring a boil, reduce heat and simmer until the tomatoes have lost their shape and it begins to resemble a chunky sauce, about 10 minutes. Remove from heat.

Remove from oven, spread on tomato sauce, layer on the cheese slices and half the basil ribbons, then drizzle with the olive.

Continue baking in oven for an addition 10 minutes, or until the cheese is browned and melty. During the last 2-3 minutes of baking, slide the pizza off the pan and directly onto the oven rack for a crispier crust, if desired. Remove from oven and sprinkle with remaining basil ribbons and season with salt and pepper.
