Four ingredients, that is all there is in this tasty, filling, and sometimes messy creation of a meal. Whether it is called a sub, hoagie or sandwich is a point of regional preference, but the ingredients remain the same.
Italian Sausage (Sweet, Hot or both) cooked in a Marinara Sauce, Sliced Provolone Cheese and a Italian / Hoagie Roll or a French Baguette is all that is required.
Making the sandwich is simple. Open the bread (6 to 12 inches in length), lay down a few slices of Provolone Cheese and your Italian Sausage from the sauce and then top with the gravy in which the sausage was simmered. The result is a hot sandwich with the cheese melted from the heat of the sausage and sauce. Each time I eat this sandwich I reminisce to the East Coast of my youth. Sitting with friends at an Italian Pizza and Hoagie Shop with a cold fountain Coke when my worries and concerns with few.
The Italian Sausage Sandwich is an easy meal to make. My only word of caution is not to be wearing your best clothes. Inevitably you will drop some sauce onto your shirt, but then that is part of the experience and memories.
