Use a large cutter or a sharp knife to cut the tortilla wraps into discs big enough to fit in a muffin tray. Place into the muffin holes and bake until very lightly browned. Allow to cool. Heat a pan and fry together the onions, garlic and cumin until lightly browned. Add the aubergines, sweet potato, 1 tbsp. olive oil and season well with salt and pepper. And soften for 6-8 minutes. Add in the chickpeas and hazelnuts, toss for one more minute and remove off the heat. Add in the spring onion, chopped coriander, ½ cheese and mix well. Adjust the seasoning and use the mixture to fill the baskets. Sprinkle the rest of the cheese on top and finish in the oven until the cheese melts. Serve garnished with rocket leaves.
