waise baat to kaan mein batane wali hai :embarrassing
actually I put nothing special. just salt, red chilli powder, haldi, garam masala powder, ginger & garlic paste and a little bit lemon juice … NOTHING else. and I cooked it under the oven grill.
you can use all kind of chicken on your pizza … boiled, fried, BBQd, grilled, out of saalan 
etc.
and seperately on pizza I sprinkled some oregano and red chilli.
