I do the same thing. I always ask what vegetables are included, and if it's not something I can have I've never had a problem getting them to replace it with something legal. But once in a blue moon, if you happen to have a few pieces of carrot, it probably wouldn't be disastrous. Sometimes grated carrot comes in a salad I've ordered. I don't pick each piece out or anything, I just sort of eat around them and avoid them for the most part.
