SAUCE & DRESSING: prepare the Special Sauce in a bowl by combining the Mustard, Mayo, Worcestershire Sauce, White Pepper, Chilli Powder together ans mixing them well. For the French Onion Dressing, combine in a separate bowl the Sour Cream, Garlic, Chives, Salt, Onions together and mixing them well. Keep them in the fridge. NOTE: the French Onion Dressing is my own flair, if you don't like it you can leave it entirely.
