I don't know about the green peppers, I personally don't like them but majority rules. lolBack on topic with the satanic pizza.
So far I have:
Pineapple pieces. I'm thinking of charring them
White sauce - possibly mozzarella and ricotta. May also use a cheese with more 'bite'.
Onion - I'm favouring red onion as I think this pizza needs the colour
Ham - I'm veering towards prosciutto or pancetta/bacon
Green stuff - not sure about green peppers. Ideas welcome
Chilli (sorry @cookieee) - Scotch bonnet
