I moved to the city a year ago and haven't seen one since, but it occurred to me last night at a little Tex-Mex place that they would be so easy to replicate.
I bought all of the ingredients for less than $10, and I made about a dozen.
1 bottle of mild salsa con queso
20 oz of chunk chicken breast
1 package of egg roll skins
Feel free to use thin tortillas or puff pastry instead of egg roll skins, so long as it's a very thin crust. If it isn't crispy, it isn't a crispito.
Step 1: Assemble The Crispitos
Spoon out a small amount onto an individual egg roll skin and roll it up nice and tight.
Initially, I'd used a bit of the queso mixture to seal up the egg roll skin, but I later found this to be unnecessary.
