Roast Beef Sandwich

Roast beef sandwiches encompass a large variety of sandwiches filled with roasted and sliced beef as their main ingredient. They may be served hot or cold. The meat should be succulent, slightly pink, and thinly sliced, while the buns are typically soft and topped with sesame seeds or onion pieces. As for the toppings, anything is possible, but in Boston, where roast beef sandwiches are one of the area's specialties, they are traditionally topped with cheese, barbecue sauce, and mayonnaise (called a three way when served together).
