My fave fast food item has always been the Zantigo Cheese Chilito. The
last time I was able to indulge in one of these was on that fateful
day in 1986 when they closed them down(after Taco Bell bought them out
through KFC).

It can't be that hard to make. Does anyone know the recipe (preferably
someone that has worked there)?

Thanks so much for that link...I copied the phone number. The only
thing is that the description of the chilito in that article was very
'chili-ish'. The original chilito is more of a cheese concoction and
it has some sort of underwhelming green substance that very well might
be some sort of chili (but the color is nowhere near brown). The
consistency is more of a whipped and gooey cheese concolction that has
some sort of airy-green substance in it.
