Preheat oven to 180°C. Line 2 baking trays with baking paper. Place chickpeas in a bowl. Drizzle with 1 tbs oil. Sprinkle with the cumin, fennel and smoked paprika. Season. Toss to combine. Spread over 1 lined tray. Bake, tossing occasionally, for 15 mins or until chickpeas are light golden. Drizzle the red onion with a little olive oil and wrap tightly in foil. Place in the oven to cook alongside the chickpeas. When the chickpeas and onion are ready, set aside to cool. Peel the onion into layers.
Finally, cut the haloumi into fairly thick slices and grill in a dry frying pan, over medium heat. Add the haloumi slices to the salad and serve.
