Part 2/8:
The foundation of any great sub is, without a doubt, the bread. For a deli-style sub, you want a long roll that strikes a perfect balance—soft but chewy, with enough sturdiness to handle the assortment of fillings and sauces. While you can purchase your favorite sub rolls from a grocery store or bakery, it’s worth the effort to make your own. A simple hoagie roll recipe, enhanced with Italian herbs before baking, can make a world of difference. Alternatively, using whole wheat flour results in a denser, chewier roll, which can add a unique texture to your sandwich.
