In a large mixing bowl, toss the pork sirloin roast with salt, black pepper, smoked paprika, mustard seeds, celery seeds, fennel seeds, Ancho chili powder, turmeric, ground ginger, olive oil, and chopped garlic until the meat is evenly coated.
Preheat your air fryer to 360°F (182°C).
Cook the pork for 30 minutes, then turn it over and cook for an additional 20 minutes until it reaches an internal temperature of 145°F (63°C).
While the pork is cooking, prepare the tzatziki.
In a bowl, mix the chopped and squeezed cucumber with Greek yogurt, minced garlic, olive oil, balsamic vinegar, dill, and a pinch of salt.
Refrigerate until ready to serve.
Once the pork is done, let it rest for 5 minutes before slicing.
Serve the pork slices with the chilled tzatziki sauce on the side.
