In a small baking dish, add the tomatoes, peppers and garlic cloves. Drizzle with olive oil and dust with salt and pepper. Toss together and bake in 400 degree F oven for 30-35 minutes, or until the tomatoes blister and garlic begins to get golden.
When done, allow tomatoes to cool for a few minutes.
In a small food processor (or you can roughly chop), add basil leaves and olive oil. Pulse together until a rough pesto forms.
To assemble: spoon basil oil on bottom of plate, then place roughly torn fresh mozzarella and top with caramelized tomatoes, peppers and garlic. Drizzle additional olive on the top.
