Wash and clean the aubergines and cut them in half lengthwise. Slice or cut 4 slices lengthwise from each half. Season aubergine slices with salt and pepper and place them next to each other on a baking tray brushed with 1 tablespoon of oil.
Coat the surface of the aubergines thinly with approx. 1 tablespoon of oil and bake in a preheated oven (electric cooker: 200 °C/ circulating air: 175 °C/ gas: see manufacturer) for 10-15 minutes.
In the meantime cut the rest of the eggplant into very small cubes. Heat 2 tablespoons of oil in a large frying pan. Fry the aubergine cubes for 5-6 minutes while turning. Wash and clean the spring onions and cut into fine rings.
Place the aubergine cubes in a bowl and season with salt and pepper.
Roast the pistachios in a pan without fat. Take them out, let them cool down and chop them into small pieces. Crumble the cheese. Wash basil, shake dry and chop the leaves of 2 stems finely. Add cheese, pistachios and basil to the eggplant cubes, season to taste.
Remove aubergine slices from the oven and let them cool down a little. Spread the mixture over the aubergine slices and wrap the ends over them, then pin them firmly with a wooden skewer. Garnish with the rest of the basil.
