• Preheat your oven to 400°F. 

Pizza Sauce

• If using diced or whole tomatoes, use an immersion blender or food processor to process your tomatoes until they are the consistency of salsa.
• In a large pot, over medium heat, heat oil. Add garlic and cook until lightly golden, 30 seconds to a minute. Carefully add tomatoes—oil will sizzle and pop as you do. Stir in sugar and basil. Bring  mixture to a simmer.
• Turn heat down as needed to keep at a good simmer and cover with a splatter screen if you have one. Simmer for 20 to 30 minutes, stirring occasionally, until sauce has thickened and reduced to about 1 1/2 cups. If you don’t own a splatter screen and the sauce is popping too aggressively, turn it down and extend the simmer time as necessary.
• Add salt to taste.

Pizzas

• Place naan loaves on baking sheets. Cover each with about 1/3 heaping cup of sauce. Top with 1/2 cup of cheese each and desired toppings. 
• Bake for 12 to 14 minutes, until cheese is melted and naan is golden. If baking all 4 pizzas at once, swap top and bottom trays once halfway through and keep an eye on the bottom tray to make sure the crust is not burning.
• Cool on the baking sheet for 5 minutes before slicing, and enjoy!
