You can buy pizza cheese (cheddar cheese) and base very conveniently from any reputed bakery shop. Spread tomato sauce on pizza base and sprinkle salt as per your taste. Spread veritable rings (onion, cauliflower, tomatoes, and capsicum). Mash cheddar cheese on the top of pizza. Spread aluminum foil and place the pizza on it. Switch on the tandoori. Let it be on for 2-3 minutes and thereafter switch it off. Let it cool for at least 2-3 minutes. Take out the brown pizza. Its ready to serve.
Precaution: Preheat the tandoori with tray for 1-2 minutes kindly take care that foil doesn't touches the heating coil
