I was just DYING for frito pie, but didn't know where to get it!

I saw this sign today (for you ABQ folks, it's at Paseo/Wyoming). It's near a grocery store and strip mall, but not anywhere near being directly outside of any particular store or restaurant.

I was bewildered by it. Who is this Dee Dee? Does she just whip up a frito pie in her kitchen anytime someone calls with a hunger deep in their belly?
