Put oil, lemon juice and black pepper in a bowl. Add finely chopped garlic, thyme, oregano and rosemary. Cut grill and frypan cheese, pepper and onion in cubes of about 2 cm in size. Place the cheese, pepper and onion cubes and the mushrooms in the marinade and turn. Marinade them covered in the refrigerator for at least 4 hours. Preheat grill. Alternate the mushrooms, cheese, onion  and pepper cubes on metal skewers. Grill the skewers on the grating for approx. 8 minutes, brushing them repeatedly with the marinade.

Enjoy!
