Good topic. I've been wanting to have a pizza night but haven't been that inspired since going veg but some or your ideas sound awesome.
I think i'd like that hot and spicy one, probably just the tomato paste, bbq sauce, chili powder, jalapenos, onions, capsicum. Maybe with vegan bacon or vegan salami - I haven't tried either of them yet, so I dunno if I like em.

and also a rosted veg one - pumpkin, potato, capsicum, onion, brocoli and a sprinkling or corn and peas and spinach. Probably nice with a margherita base. I'm not sure what herbs they put in the sauce to make it so yummy.
I'm not very good at fresh herbs, though I've been thinking about setting up a little herb garden. Would probably help with adding flavour to dishes, right now I only use garlic, curry and chili powder in any dish haha.
I've had a puffpastry pizza before with just tomato paste, onion, peas, carrot and corn mix and bbq sauce with a bit of toffuti cream cheese. That wasn't too bad, but the others sound divine.
Do you guys put cheese on? I stillll haven't tried vegan cheese. I went to buy some cheezly, happy to pay 8 dollars for it, but then I saw how tiny the little log was and I decided I'd live without. Though I still really would like to find a good cheese. (Specially since the omni bf is a cheese freak

) Might have to just suck it up and buy it.
