The perfect thing for Halloween. Baked brains, but really it's just pizza over a whole head of cauliflower.
Start by setting out the spice profile: basil, onion powder, salt, garlic and oregano. Stir it in the tomato paste and mix thoroughly. Wash and shake dry a head of cauliflower.
Spread the spiced tomato paste on the cauliflower and cover with thinly-sliced vegetables.
