At present? Cinnamon rolls. Ask me again in a week, and I'll probably have a completely different answer. Our firstborn basically lived on mac and cheese for the first 10 years of his life, but DD is all over the map (or all over the food pyramid) with her food likes and dislikes. When she was a toddler, the best way to keep her quiet and amused in the supermarket was to get her some broccoli to munch on from the salad bar.
More shocking to us was the year we spent in CO, where we discovered that many restaurants there didn't have a pasta or mac 'n' cheese selection on the kids menu. WTH?!?!
