Years ago when I was at college we had a little sandwich stop nearby that did the most amazing sandwich filler of "Chinese" chicken in a lurid pink mayo - it wasn't authentic obvs.
BUT it was bloody lovely - filled to the brim in a brown roll with cheap spread and weird random salad (carrots, cabbage, stinging raw onion and a lonesome tomato) This is when I lived in Yorkshire / Co. Durham so maybe it's just a regional thing??
Anyway, I've recently remember how much I loved it but looking on Google only brings me 1kg catering / trade tubs of it. There doesn't seem to be a recipe I can steal either! Any ideas? Many thanks!
