Toasted sourdough pastrami sandwich, with spinach, red onion, avocado, red capsicum, homemade pickles, mayo and mustard. It was decidedly too big to eat in typical sandwich form, so this was how it was consumed.
Wrap form (cos lettuce instead of spinach):
Not arguing, I looked up what the different types of sandwiches are, and Wikipedia does include open-faced sandwiches.. So maybe it's just one of those things that are more of an opinion thing, or varies by country?
Though I do agree, that "sandwich", in the traditional sense, is ingredients between two slices of bread.
