These Italian Chicken Subs are piled high with seasoned chicken, sauteed veggies, melted provolone and a unique sandwich spread that adds a tangy kick and puts this sandwich over the top!
I’ve got a thing for sub style sandwiches.
Sometimes it just feels like a sandwich kind of night and in order to satisfy the people I feed in this house it’s got to be hearty and flavorful. I’m adding this recipe to my collection today and it it’s sliding in nicely, right next to my Slow Cooker Drip Beef Sandwiches and my Crock-Pot Chicken Philly Cheesesteak Sandwiches – also delicious choices!
Although it bears some similarity to the others, there is something pretty special about this tasty sub that sets it apart from anything I’ve ever done before.
The most interesting component to this recipe is the incredibly simple but unbelievably flavorful Giardiniera Sandwich Spread. It consists of just two ingredients, takes a minute to put together, and stores nicely in the fridge for a week or more.
Lets make some Italian Chicken Subs!
I love to use a cast iron pan to sear chicken and other meats. Ignore the fact that there are just two lonely pieces of chicken in that pan. Use up to 6 pieces, depending on how many you’re feeding. Thin-sliced chicken will work best so slice them through the center if you’ve got the thicker cut.
The chicken is cooked in olive oil over medium-high heat and seasoned with a little garlic pepper, oregano, and salt.
Remove the cooked chicken from the pan and add a touch more olive oil. Add a couple of sliced red bell peppers, a sliced onion, and some minced garlic to the fond in the pan. What the heck is fond? Fond is what is left behind in the pan after you cook your meat and it is your best friend when cooking veggies. Browned bits of meat and sauce and trace amounts of the seasonings you used is going to add so much flavor of your veggies.
Cook, stirring occasionally, until the peppers and onions have softened.
Spread a good layer of the sandwich spread on a hoagie bun and layer it with the cooked chicken and veggies. Top the subs with a slice of provolone, an excellent cheese that melts wonderfully, and pop it under the broiler until it’s toasty and melted and fabulous!
