I am a reformed donner kebab addict, limit myself to one a month now!! so this topic has interested me. I knew the owner of Sinbads kebab house on (central drive here in Blackpool,uk) It has shut down now but made the best homemade sauces , i tried and tried to get him to show me how the chilli sauce was made, but he couldnt give his successful trade secrets away (people used to drive from miles away just to buy tubs of his sauces &kebabs!)He always gave me extra meat and sauce though!
bitchinsahsa's description sounds very similar, it definately had fresh black pepper in it, how i miss that place
ps- (cant stand that hot bolognese type that some places use, heats up the salad and makes the pita soggy) ps-2 damn u guys, got a craving now tonite....and the kebab shops here are open to 3am!!!! must resist, think of the cals....resistance is futile....
