Pineapple,Garlic, Black Olives,Ricotta Cheese,Goat Cheese,Pine Nuts,Basil Pesto are all additions I would desire... offering a list of possible "Extras" I think on top of either Red or White Sauce is desireable.. also add some Chicken..
I remember a Pizza Place in Santa Cruz when I lived there in the 1980's that had some kind of Cashew Sauce that was incredible... they had all kinds of *Healthy* ideas...baked Tofu? I wish I remembered the name circa 1983-7. it was on River St right up from Scribner Park near the Clock Tower...
