Clean, wash and slice the aubergine. Clean, wash and slice the zucchini lengthwise into thicker slices. Halve, clean, wash and cut the peppers into thick strips.
Wash the rosemary, dab dry and, except for something to garnish, pluck coarsely. Peel the garlic, halve 1 clove of garlic and finely dice 1 clove. Rub the grill pan with oil and halved garlic cloves.
Fry the vegetables, rosemary and halved garlic cloves in portions while turning for 2-3 minutes. Season with salt and pepper. Take out and mix with 3 tbsp. oil and finely diced garlic and place on a baking tray.
Keep warm in the preheated oven (electric cooker: 175 °C/ circulating air: 150 °C/ gas: level 2). Wash the meat, dab dry and season with salt. Coat each steak thinly with 1/4 teaspoon of oil. Fry in a hot grill pan for 3-4 minutes on each side.
Remove meat from the pan, season with pepper and wrap in aluminium foil. Let it rest for a short time. Arrange grilled vegetables and rump steaks on plates. Baguette tastes good with them.
