Cheesy Beefy Melt (tm)

Found somewhere on the internet, but not NW Arkansas unfortunately. I thought the combo of Mountain View and Wal-Mart would be a slam dunk for an Arkansas-based post, but when you throw Atherton into the mix, you learn that we're talking about the Bay Area. Also, baby-sized burritos should have been a dead giveaway, since they don't exist this side of the Sierras.
