01 - Heat the oven to 375°F. Line a rimmed baking sheet and lightly oil it. Cook the turkey bacon according to its package, then crumble it; use cooked bacon in the filling.
02 - Mix softened cream cheese, cheddar, bacon, garlic powder and onion powder. Add pepper and only a little salt, since the chips and cheese already season the dish.
03 - Cut a pocket along the thick side of each breast without cutting through. Divide filling into four portions. Fill only what each pocket can hold and reserve any excess in a small oven-safe dish for separate thorough cooking. Secure openings with toothpicks, counting them.
04 - Set out flour, beaten eggs and crushed chips in separate shallow bowls. Dust each breast with flour, dip in egg, then press into the crumbs. Discard coating mixtures that touched raw chicken.
05 - Arrange with space between pieces and mist the tops with cooking spray. Begin checking at about 25 minutes; continue until the thick chicken and center of the filling reach 165°F. Shield a darkening coating loosely with foil if needed.
06 - Rest briefly and remove every toothpick before serving. If filling escaped, check it is thoroughly heated before serving it with the chicken.
