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 1/2" thick. Sprinkle with salt (1 teaspoon) and pepper (1/2 teaspoon).
Breading. Place crushed pork rinds (1 cup) in a large shallow bowl, and combine with 1/2 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 (1/4 cup), and shredded provolone cheese (1/2 cup). Finish with the remaining 1/4 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!
Notes
Crushing the pork rinds - Do this in a large resealable bag with a rolling pin. Or, grab a bag of pork panko on Amazon.
Not a fan of pork rinds? You can fry chicken using my low carb chicken nuggets breading. NOTE: this breading must be fried in oil, as it won't "puff" up in the oven.
Spaghetti sauce - most products contain added sugar, so read labels carefully. Trader Joe's has a few sugar free options, as well as Simple Truth (at Krogers).
