Sandwich Box wins my own personal contest for Best Sandwich in Toronto. Hands Down.
They're big, and tasty, and they definitely don't skimp on the toppings. They have grilled eggplant, grilled mushrooms, avocado, roasted red peppers, caramelized onion... I'm drooling just thinking about it.
I used to work beside a Sandwich Box and it was perfect for a grab-and-go lunch. My husband and I will also sometimes get it to bring to Toronto Island with us, since it comes in a handy little box and is served with a salad.
They use Ace Bakery buns, and their spreads are clearly labelled if they're vegan or not (tip: pick two spreads and have them use one on one side of the bun, and the other on the other side).
