Clean the washed peppers and quarter them lengthways. Place on a baking sheet skin side up. Roast in a preheated oven at 225 ° C for about 15-20 minutes (the skin then forms dark blisters). Remove.
Cover with damp kitchen paper and leave to cool for approx. 10 minutes, then peel the skin.
Wash and pluck herbs. Mix the vinegar, salt, pepper and sugar, beat in the oil and thyme. Cut the cheese into 12 pieces and turn them in them.
Roll a piece of cheese into a pepper quarter and pin it (with toothpicks). Drizzle with the marinade and let it steep for at least an hour. Garnish with basil leaves.
