When I travel, it takes a while before I miss any particular food; I really enjoy tasting new dishes and eating food that is not so familiar to me - in my opinion, that is an important part of travelling, of experiencing something new. However, at some point I begin to crave for fresh fruit - and not for pieces of fruit you get in a fruit salad, but for, say, a whole apple or a pear... Another thing I usually miss after some time of travelling is Finnish rye bread. There's nothing like it anywhere else (not that I know of, at least). It is very dark because it is made entirely of rye flour. I particularly like it when it is whole meal with lots of whole grains in it. Yes, it is probably one of the healthiest food in the world (plenty of fibre, vitamin B etc., very low on fat…) but still, I'm almost addicted to it, I hardly ever eat any other bread. The only "substitute" for this that I have found is German "vollkorn brot", which looks pretty much the same. However, where I've seen it, it has been wrapped in plastic packages to preserve it for a long time, so it doesn't taste very fresh and though the ingredients are much the same, the taste is nothing like that of the Finnish bread I like.
