The only food I know of from the UK is like...... haggis : p
Oh but my boss went to the UK once, and he said his biggest complaint was the food, I guess he did not like it : p
I have some Canadian friends and they tell me a bit about food from there, like the dressed up chips and like milk in a bag, which I guess is common in like Quebec or something : p Haha Canada is weird with food apparently : p
