In a mixing bowl, combine Greek yogurt, Tandoori Masala, aamchur powder, chili powder, salt, and oil. Mix until smooth.
Add paneer, pineapple, onion, and bell pepper. Toss gently until everything is well coated. Cover and refrigerate to marinate for at least 1 hour.
Thread the paneer, pineapple, and vegetables alternately onto skewers.
Preheat air fryer to 375°F (190°C).
Arrange skewers in a single layer in the air fryer basket.
Air fry at 375°F for 10–12 minutes, turning halfway through, until the paneer is golden and charred at the edges.
Serve hot with cilantro-mint chutney or a squeeze of fresh lemon!
