My idea of an extreme mash up would be, Lady Grantham (Maggie Smith’s character on Downton Abbey) at the dining table suspiciously eyeing a Vietnamese Sandwich on a plate before her, in her peevish upper-crust British accent, “You can’t be serious! Am I expected to pick this up with my HANDS, like a scullery maid, picking up a scrub brush?”
Thank goodness I am not a member of aristocracy because I have no prejudices against eating food with my hands. Sandwiches are not something I eat a lot of, perhaps because of the bad press they have gotten ie, Wheat Belly, Hi Carbs, Gluten. But there are times when nothing satisfies like a sandwich, especially when it is a Vietnamese sandwich called the Banh Mi.
