The sandwich has been the staple of the midday meal since the turn of the century. But despite its commonality, the sandwich is anything but boring—at least in Portland. Take the ones at Bunk Sandwiches, which come stuffed not with common cold cuts, but with house-cured pork belly. Or the burgers at Little Big Burger, which feature pillowy brioche buns bursting with locally made meats and cheeses. And of course, you can’t forget the traditional grilled-cheese sandwich, though the ones at Brunch Box are anything but traditional. The crispy, cheesy concoctions function as hamburger buns, bookending a massive beef-and-turkey burger to create a sandwich-on-sandwich-on-sandwich masterpiece.
