Remove the pork from the refrigerator to allow it to come to room temperature.
Peel and cube the sweet potato in about 2" cubes. Place on the tray and drizzle with olive oil. Sprinkle over the spice blend, making sure to reserve enough for the pork and the apples.
Place the sheet pan in the Ninja Foodi Digital oven and select the air roast function on 400°F/200°C. Set the time for 15 minutes.
Remove the tough stems from the asparagus. When the sweet potatoes have been cooking for 10 minutes, add the asparagus to the pan and drizzle with olive oil and season with salt and pepper to taste. Resume cooking at 400°F/200°C on air roast for another 5 minutes.
While the asparagus is cooking, slice your apple into wedges. I don't peel it, but you certainly can. If you want very soft apples, cook them when you start the sweet potatoes. If you want soft, but not very soft apples, put them in when you add the asparagus. Drizzle a little olive oil on the apples and sprinkle with the spice blend, reserving enough for the pork.
Season the pork on both sides with the spice blend and put about 1-2 tsps of apple butter bourbon bbq or apple butter on top of each one and spread it out.
When the 15 minutes is up, place the pork chops on the tray with the apples. Select air crisp on 325°F/165°C for 8 minutes. Always check the temperature of your pork and make sure it is 145°F/63°C before removing from the oven. Allow to rest for 5 minutes.
Serve & Enjoy!
