My other secret food is goldfish crackers. I've always loved them, and since the kids were little, we always have them around. Very dangerous. Call me old fashioned, but I still like the cheddar ones best (no, not the cheddar with whole grain or the calcium enriched ones. WTF?)
(I love that Wikipedia has articles on goldfish crackers and instant noodles. The fact they're serious articles is even funnier.)
What's your secret food?
