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.
Branston Pickles is one way. Or a slice of pickled cucumber from “Spice Girl” in Rotterdam - they pickle their cucumbers with habaneros.
Pepper butter is another way to improve a sandwich. Or tomato butter made from blended dried tomato in oil mixed with butter. The addition of oil makes it an easier spread, too, but don’t use olive oil here, it easily gets bitter in the blender.
