Prepare the mushrooms. Heat oil in a skillet over medium high heat. Add onions and mushrooms. Stir and cook for 2-3 minutes. Transfer the mixture into a bowl and let it cool at room temperature for at least 20 minutes.
Prepare the chicken. Season both sides of each chicken breast with black pepper, salt and Italiano seasoning. Place each chicken breast, one at a time, between 2 sheets of plastic wrap or in a ziploc freezer bag. Carefully flatten the chicken breasts with a rolling pin until they are approximately ¼-inch thick and 6-inches wide.
Stuff the chicken. Place one chicken breast on a clean sheet of plastic wrap. Add ⅓ cup baby spinach on top of the chicken breast. Reserve 1-2 tablespoons of the mushroom and onion mixture, and then add a third of the mushroom and onion mixture on top. Make sure to spread the filling evenly, leaving a ½-inch border around edges.
Roll the chicken. Tightly roll the chicken into a log, and wrap tightly in plastic wrap. Once wrapped, grab the two ends of the plastic wrap and roll to twist them and make it extra tight. Use plastic clips to secure both ends. Repeat these steps with the remaining two chicken breasts. Transfer the chicken rolls in the refrigerator and let them set for 30–60 minutes.
Add the breaded coating. Take the chicken rolls out of the fridge and remove the plastic wrap. Take two shallow plates and add eggs to one, and panko breadcrumbs to the other. Dip each chicken roll into the beaten eggs and then, roll in the panko to fully coat.
