Cut the boneless pork ribs into bite-sized pieces. Season with salt, pepper, and garlic powder to taste.
Lightly grease the air fryer basket with olive oil or line a baking sheet with parchment paper. Arrange the pork in a single layer, leaving space between each piece.
Air fry at 350°F for 15 minutes, flipping halfway through. Use a meat thermometer to ensure the internal temperature reaches 145°F.
While the pork cooks, melt butter in a small skillet over medium heat. Stir in Parmesan cheese, and optional seasonings like red pepper flakes or Italian seasoning.
Transfer cooked pork to a large bowl. Pour the butter Parmesan sauce over the pork and toss with tongs until evenly coated.
Plate the pork bites with your favorite sides, such as mashed potatoes, roasted vegetables, or a fresh salad.
