You will also need
Cook the Italian sausage
- Heat the oil in a large, non-stick skillet over medium heat. When the oil is hot, add the sausage. Cook the sausage for 4-6 minutes, turning them occasionally to brown on all sides.
- Carefully add the water to the skillet and cover.
- Cook the sausages for 15-20 minutes until most of the liquid has cooked out and the internal temperature reaches at least 165°F. Use an instant read thermometer to make sure.
- Take the skillet off the heat and remove the sausages. Place them on a plate or pan and keep warm. Loosely cover the pan with foil and/or place in the microwave it should stay warm away from drafts.
Cook the onions
- If there is any liquid left in the skillet drain it off, but do not wash. There should be a layer of oil, if there’s not, add one teaspoon.
- Heat the skillet on medium. When it’s hot, add the onions. Cook them gently until they turn a nice golden color, approximately 5-7 minutes.
- Stir the onions frequently so they don’t burn. Remove the skillet from the heat and build the sandwiches.
Preheat the oven
While the onions cook, move the oven rack to the bottom third of the oven so that the sandwiches are not sitting too close to the heating element. Set the oven to the low broil setting.
Build the Italian sausage sandwiches
Cut each sub/hoagie roll to roughly the size of the cooked sausage. Then cut the bread in half lengthwise, but don’t go all the way through, like butterflying.
Add two tablespoons of the marinara sauce to the bottom piece of the roll and sprinkle with about 2 tablespoons of mozzarella cheese.
Add one sausage to each roll and top each with two tablespoons of marinara sauce, cooked onions and 2 tablespoons of shredded mozzarella cheese.
Arrange the Italian sausage sandwiches on a baking sheet. Place the baking sheet in the preheated oven. Broil the sandwiches for 4-5 minutes or until the bread is lightly toasted and the cheese is melted.
Keep an eye on the sandwiches, turn the oven light on and watch them carefully. Do not step away from the oven. The sandwiches will toast very quickly and can go from beautifully toasted to burnt in no time!
Garnish with a little parsley if desired and enjoy.
