Sheet Pan Sausage and Pepper Subs

Sub. Sandwich. Hoagie. Grinder. Hero. 

Whatever you call it- I call it the makings of a delicious dinner!

These sausage and pepper subs call for a bit of slicing. Then, help the kids with their homework or go for a quick walk. Within 30 minutes, dinner will be READY TO EAT! That's right! One sheet pan, a few minutes of prep, and dinnertime happiness.

You could even slice the onion, peppers, and sausage ahead of time. Simply add olive oil, salt, and pepper before roasting. Some people also prefer adding a little tomato sauce just before serving.

Difference Between Hoagies and Subs

Both are delicious sandwiches and these terms can sometimes be used interchangeably. If you're from Philly or New Jersey, hoagies are sandwiches that are at least 6-inches long. Closely associated with Italian-American culture, they often contain ingredients like salami and provolone. They are served cold and piled high with meats, cheese, toppings, and sometimes a dressing. Another type of sandwich- subs can be served hot or cold. Pretty much anything can go inside- meatballs, chicken parm, turkey, roast beef, cheeseburger, and so much more! The name comes from the submarine-like shape of the roll. 


What is a hero?

Hero is another name for a sandwich. The term was coined by a writer in New York City. In 1936, she referred to a sandwich so large "you had to be a hero to eat it."
