Craig, because i learned so much from you, heres 1 tip for you, maybe you already know it, wouldnt surprise me.
CARAMELIZED ONIONS IS THE GREATEST THING ON EVERY PIZZA EVER.
Literally, it makes every pie i have created better.
'Nduja, olives and then caramalized onions(caramelize, bit of salt, bit of brown sugar, done) after bake.
Have you ever tried caramelized onions on pizza?
