FOOD
I think it would be roast chicken (preferably leg), chips (fries) or roast potatoes and garden peas.
However I adore raw tomatoes, and in fact when I was 19 and very ill with measles I actually did live on them for a week - it was the only food I ate.
Fruit would definately be pineapple.
DRINK
Hard - I love cold tap water, but some places don't taste as nice as others, so maybe I had better say squash. There is one I love, which is actually a cheepo brand, but I find it better than most.
However how can I lose a cup of strong tea? ... so can I cheat and have both, please.
