1Peel the potatoes and cut them into small cubes.
2Slice the red onion into half rings.
3Drain the chickpeas in a sieve and rinse briefly with cold water.
4In a large bowl, mix the pumpkin cubes, potatoes, onion, chickpeas, cumin, thyme, paprika, and a drizzle of olive oil. Stir well, then transfer everything to the air fryer basket. Cook at 180°C (350°F) for 20-25 minutes, shaking the basket halfway through.
5Sprinkle the crumbled feta cheese over the cooked vegetables, then cook in the air fryer for another 10 minutes until the cheese is lightly golden.
6Serve the casserole hot, directly on plates, optionally with fresh herbs or a yogurt sauce.
