For the marinated vegetables, wash and clean the peppers and cut them into strips. Clean and slice the eggplant, zucchini and mushrooms.
Put the vegetables in a perforated cooking container and cook (at 100°C for 3-4 minutes).
Make a marinade with olive oil, wine vinegar, white wine, garlic, salt, pepper, sugar and herbs.
Arrange the vegetables on a platter, pour the marinade over them and leave to infuse for a few hours.
