Create a quick tomato sauce by simmering tomato paste, water, garlic, avocado oil, salt, and sugar in a pan until it thickens.
Take a fresh piece of naan and spread half the sauce evenly. Add a few dollops of pesto or basil paste, then top with mozzarella, 3 slices of tomato, and 3 rounds of mozzarella cheese. Finish with a sprinkle of Pecorino Romano.
Broil for 2 minutes. If you prefer a crispier bottom crust after baking, simply transfer the pizza to a skillet and fry for a minute—no oil needed.
Sprinkle with more grated cheese. Garnish and cut into 4 pieces. Enjoy!
