Vegetable sandwich

Thinly chop the zucchini and aubergine lengthways, cut the tomatoes into thin circles, cut the cheese into thin slices and split in half. Grease vegetables on all sides with olive oil, sprinkle with herbs, salt. Place on a rack and bake in a highly heated oven for about 10 minutes. During this time, you need to turn the vegetables to the other side once. Mix the mustard with the vinegar and sugar.
