Sandwiches are the bread and butter of many Montreal restaurants often a culinary ad-lib of filling between slabs of brown or white (bagels or baguettes for those with discriminating taste). But some local eateries are experimenting with alternate ways of making the classic lunch item. Maybe club sandos don't always work best on toast and sometimes grilled cheeses can use a touch of sweetness. These unconventional sandwiches are the best thing since sliced bread, and they don't even use any.
