What is wrong with all of you I could'nt have a cheese burger any other way Tomatos, onions, lettuce, pickles,mayo, special sause, ketchup, and of course MUSTARD it like... holds the whole burger together when you are eating. Mustard helps combine flavors of every thing else making every bite you take better than the last untill the very last bite you have reached bliss
Just my thoughts on the subject.
