Cook the pasta in 3-4 l boiling salted water (1 teaspoon salt per litre) according to the package instructions.
Wash and clean the aubergine and cut into slices of about 2-3 mm. Season lightly with salt. Wash and halve the tomatoes. Roast sesame seeds in a large pan without fat while turning them golden brown. Take out.
Heat the oil in the same pan. Fry the aubergine slices on both sides for 2-3 minutes. Add the tomatoes and fry for another 2 minutes. Season with pepper.
Lightly drain the olives and chop them finely. Crumble the feta. Stir pesto with half of the feta until creamy. Stir in chopped olives. Pour the pasta into a sieve, drain and put it back into the pot.
Mix the pimped pesto well with the spaghetti. Fold in the aubergine-tomato mix. Sprinkle with sesame seeds and the rest of the feta. Veggielicious!.
