PB&J. I'm totally plebian. I've been eating them for most meals for the past while. (I'm most of the way through my third loaf of bread.) They're too easy/yummy/convenient.
I've been wanting to get some good chips, but the stores near where I live don't have the particular variety of the particular brand that I want. (<a href="http://www.seasonssnacks.com/seasons_sweet/item-detail.cfm?cat=5">Michael Season's Ripple-cut</a>)
It makes me want to open my own corner store, just to have a supply of potato chips and pasta that doesn't close at midnight/11pm.
