Saw this on the Menu Today... What?

So here I am. Considering ordering some pizza, I'm working on a Primo Meats to go and customize and lo and behold, Refried Bean Sauce.

I googled it, and it seems that it was a sauce they used on a Taco Pizza a long time ago - one of which I never tried. I worked at Pizza Hut (an NPC franchise) for about 4 years from 2003-2007 and never heard of this.

Anyone else know if this is legit and back and for what reason?

INB4 - Yes I ordered it to see if they would call me and say "we don't have that sauce". No call yet. Will update.

Edit: They just called and definitely don't have the refried bean sauce. Damn I was going to suffer through it and try it.
