Prep. Preheat an oven to 450 F and line a baking sheet with parchment paper.
Chicken. Slice chicken breasts (2) in half lengthwise. Place 1 at a time in a large resealable bag (or between 2 sheets of saran wrap) on a level surface. Use the smooth side of a meat mallet to pound chicken until each breast is ½" thick. Sprinkle with salt (1 teaspoon) and pepper (½ teaspoon).
Breading. Place crushed pork rinds (1 cup) in a large shallow bowl, and combine with ½ cup parmesan. In a second large shallow bowl, beat eggs (2). Dip each breast into the eggs, then the pork rinds/parmesan. Press the breading into the surface so it adheres. Place chicken on the prepared baking sheet.
Cover the chicken with even amounts of spaghetti sauce (1 cup), shredded mozzarella (¼ cup), and shredded provolone cheese (½ cup). Finish with the remaining ¼ cup of parmesan cheese.
Bake in the preheated oven for 25 minutes -- you'll know they're done once the chicken's internal temp reaches 165 F. Sprinkle with fresh basil, and enjoy!
