Traveling Vegetables

HELP!!!!!!!!!

We're visiting relatives about 1 1/2 hours away on Easter. I have been asked to bring homemade bread (I can do that) and vegetables.

How in the world do I bring a vegetable dish when we're traveling that far? I can put together a raw veg platter, but as for a hot vegetable dish, I'm drawing a blank.

Crock pot is a possibility. But I need ideas!
