Preheat the oven to 180 degrees. During this time, brush a baking sheet with a little olive oil, remove the seeds and white inner membranes from the peppers and cut lengthways into strips about three centimeters wide, cut the halved onions lengthways into slices, finely dice the garlic, pluck the rosemary needles from the branches and cut into small pieces.
Place the paprika strips on the oiled baking sheet, sprinkle with garlic, rosemary and herbs from Provence, finally lay out the onions in individual strips and season everything with the sea salt and drizzle with good olive oil.
Bake in the preheated oven for about 40 minutes, mix once after 20 minutes and then finish cooking. I served a beef mince steak with fried potatoes with this Mediterranean vegetable.
