Preheat the grill to high with the Ninja Foodi Grill, setting the cooking time at 12 minutes.
Season the ribs with the seasoning of choice.
Spray the grill grate with cooking spray (grapeseed etc.)
Place the country style ribs on the grill grates in the Ninja Foodi.
Coat with about 1/4 cup sauce.
Cook for 10 minutes, carefully open the lid, turn the ribs and add more sauce.
Continue cooking for 2 minutes until they reach 165 degrees internal temperature.
Note: I typically use olive oil cooking spray for this recipe without an issue; however, the smoke point is not as high for olive oil, so Ninja recommends Grapeseed or Avocado, see more here about smoke points.
