We have Tandori here - generally Tandori Chicken, rather than any other meat (I couldn't imagine Tandori Beef!)

I'd never considered it on a pizza though - I think it's the perfect combination! I can't see a "ready-made" option in the supermarket here but a home made version shouldn't be difficult to make!

Asian food is very popular in the UK - every town has multiple curry houses - It's almost ubiquitously classified as Indian food. I'd assume it fairly authentic too given the accompanying Asian population, but probably lower chilli levels to cater for our softer pallets 🙂
