Using commercially made sausages brings the "snouts & jowls" content, which I'm sure is an important component of any fast food product

Best sauce so far was a mix of yogurt, ranch dressing and scotch bonnet sauce, maybe 4 parts yogurt to 3 parts ranch dressing and 2 parts hot sauce. It was important to have sauce all through, not just on top. I tried spreading a bit of sauce on the inside of the pita before assembling but that seemed to weaken the pita and make the result kinda messy, but alternating filling & sauce a couple of times worked well. When the sauce distribution was right these graduated from "OK" to "pretty darned good".
