Does anyone know what Favorite Fried Chicken put in their Tangy Tomato Sauce for their Wrappas? I was in London for two years and just loved their wrappas but I am back in South Africa now and we don't have any Tangy Tomato Sauce available in our stores, only normal Tomato Sauce.
From looking at their website I get the impression they are not a big franchise, I certainly haven't heard of them.
I reckon it is unlikely they have in-house development chefs and are probably buying in their sauces from wholesalers. I've had a look through a few fast food wholesale websites to see if they have anything matching your description but haven't found anything.
