Grilled Italian Sausage Sub with Onions and Peppers

For years there has been a steady migration of fans from the stadium to the couch. I get it. The atmosphere may not quite be the same at home, but the tickets are free, the adult beverages come in well under $15/drink, the view on the big screen is better than just about anything in the stadium, and there is usually no line at the restroom. In 2020, the migration from tailgating to homegating before the games has become just about 100%. One of the great things about homegating is that the food is WAY better than anything you can get at the game. So let’s dive into one phenomenal game day recipe.


  • 4 (6-inch) sub sourdough rolls
  • 2 tablespoons canola oil or light tasting olive oil, divided
  • 2 cups shredded mozzarella cheese, divided
  • 1/2 large white onion, cut in strips
  • 1/2 red or orange bell pepper, cut in strips
  • 1/2 yellow or green bell pepper, cut in strips
  • 1 tablespoon salted butter
  • 1 teaspoon smokehouse salt
  • 16 ounces ground hot Italian sausage or mild Italian Sausage
  • 1 (20-24 oz) bottle marinara sauce
  • 2 cups shredded mozzarella cheese
  • 1/4 cup shredded parmesan cheese
