Cut the garlic bulb in half crosswise. Wash the tomatoes. Cut large tomatoes in half. Wash the thyme and remove the leaves. Wash and chop the rosemary. Put everything on a tray. Season with salt and pepper and sprinkle with 5 tablespoons of oil. Bake in a preheated oven (electric cooker: 200 °C/circulating air: 180 °C/gas: see manufacturer) for about 30 minutes.
Heat 1 tablespoon of oil in a frying pan. Dab the steak dry and fry on each side for about 2 minutes. Season with salt and pepper and remove. Push the tomatoes together a little on the tray. Place the steak in the middle and continue to fry for about 15 minutes.
Wash the arugula and cut it coarsely. Remove the tray from the oven. Let steak rest for about 5 minutes. Then cut into slices. Season to taste with salt and pepper. Sprinkle rocket on top. Ciabatta tastes good with it.
