Last week Jack in the Box expanded their breakfast menu to include brunch bowls, and this week Domino's Pizza has announced plans to introduce submarine sandwiches. The pizza delivery chain will offer four different kinds of baked sandwiches, including a Chicken Bacon Ranch sandwich and a Philly Cheese Steak sandwich. The $4.99 sandwiches will be delivered with or without a pizza order.With the sandwiches, which are available to order beginning on Aug. 25, Domino's hopes to increase lunch sales. Last Spring, Pizza Hut added pasta to their menu, so it's no surprise that Domino's is looking for other ways to grow profits. What do you think about the expansion? Will you try Domino's sandwiches?
