This site has received requests for the receipe to Gino's 'Secret' Sauce, especially used on Gino Giant Sandwiches. I have been told by former employees that the sauce came pre-mixed in tubes and a device similar to a caulking gun was attached to the tubes and used to apply the sauce to the sandwich.
However, I have been told that a mixture of mayo, ketchup and chopped pickles/relish (similar to Thousand Island Dressing) produces a sauce very close to what Gino's used.
