I normally have pretty basic tastes when it comes to sandwiches: meat, cheese, mayo, a spread of some kind and/or lettuce if I have some on hand. But it’s nice to throw in something different now and then.
Sticking to one or two ingredients (this is the dull men’s club after all) how do you all like to kick up your sandwiches a bit?
I’ll start-- it’s nothing crazy, but Aldi sells a Bavarian sweet mustard that’s a really nice step up from regular yellow mustard for a ham & swiss.
I’ve done the garlic salt on grilled cheese before as well, but it’s been awhile!
Related… one thing my wife taught me is to use mayo in place of butter on the outside of the bread. It doesn’t change the flavor much but it browns nicely and helps crisp up the bread.
