In a large bowl, combine ground chicken, sun-dried tomatoes, Parmesan cheese (if using), garlic, Italian seasoning, salt and black pepper. Mix until just combined, using a fork or your hands.
Shape into 4 even patties, about ½ inch thick each.
Heat canola oil in a large skillet over medium high heat. Add the burgers to the pan when hot and cook for 5-6 minutes. Alternatively, you can cook these over a well-greased grill on medium-high heat.
Flip the burgers over, add a slice of mozzarella to the top of each one and cook for another 4-5 minutes, until the burgers are done. If your cheese isn’t melting enough, you can cover the pan with a lid during the last minute of cooking time to help it along.
Let rest for a few minutes so the burgers retain their juices. Serve hot on burger buns with desired toppings and enjoy!
