First place the red peppers on a baking tray and roast them in the oven until charred. Peel off the skins, remove the seeds and arrange them in a dish. In a bowl mix the olive oil, salt and vinegar. Peel the garlic, chop it finely and stir it into the olive oil. Pour this mixture over the red peppers. You can serve it garnished with fresh thyme. Enjoy your meal!
