Add approximately 1/3 cup of pesto to each medium pizza or 1/2 cup to each large pizza. Add a layer of mozzarella, season with a little sea salt and fresh cracked pepper. Grill or bake at a minimum of 500 degrees, preferably on a preheated pizza stone, or on a large, inverted, preheated cast iron skillet. Depending on how hot you can get your oven or grill, the cooking time will be anywhere between 5-10 minutes. You are looking for golden brown crust and bubbling cheese.
Remove from the oven and top with the prepared Simple Arugula Salad and serve immediately.
