Add marinara sauce and chopped basil to a medium bowl. Stir to combine and set aside.
Spray a 9 x 13 inch baking dish with non-stick cooking spray.
Butterfly the chicken breasts. Place chicken breasts on a cutting board and top with parchment paper or plastic wrap. Using a mallet or the backside of a small skillet, pound the chicken breast to approximately ¼ inch thickness. Salt and pepper both sides of the pounded chicken.
Grab a handful of toothpicks out of the box and place on your workstation.
Mix bread crumbs and ½ cup of the parmesan cheese in a small bowl.
In another small bowl, whisk the eggs.
Take the first piece of chicken and spread a spoonful (1 to 2 tbsp. depending on how saucy you like it) of marinara sauce on it. Add 1 slice of cheese.
Roll up the chicken tightly and secure the seam with toothpicks. (Be sure to count the number of toothpicks used, so they can be removed before serving.)
Dip the roll-up in the egg and then the bread crumb mixture. Be sure to coat the roll-up with bread crumb mixture evenly on all sides. Complete with all chicken breasts.
Pour remaining marinara sauce in the bottom of the baking dish.
Place the breaded chicken roll-ups in the baking dish, seam side down. Top chicken with remaining parmesan cheese.
Bake for 25-30 minutes or until no pink is visible in the chicken and the juices run clear.
Serve over whole grain or gluten-free pasta with a side of roasted broccoli or green salad.
