Cut the eggplant crosswise into approx. 5mm thick slices. Toast without salt and oil in a pan or on the grill until light brown. Spread on a plate, drizzle with balsamic vinegar and olive oil and season with coarse salt and pepper.
Before serving, pluck the rocket into bite-sized pieces and cover the aubergines with it. Season again with a little olive oil, lemon juice, salt and pepper and sprinkle with parmesan shavings. Finished!
