If you can find Telera rolls, by all means buy them. A Telera roll is very soft both on the outside and inside, but still sturdy enough to hold the heavy ingredients in this recipe. A Bolillo roll is another popular bread used in Mexican sandwiches. It has a football shape, a crustier outer crust than a Telera and the inside is soft and chewy. An easier to find Hoagie roll will work great for this recipe. Both of these rolls are smaller than a sub roll.
