Wash the meat and pat dry. Fry in 1 tablespoon of hot oil on each side for about 4 minutes, season. Let it cool down
Drain the tuna. Peel the garlic. Puree both with salad cream, yoghurt and 1-2 tbsp. capers, season to taste
Clean, wash and pluck the rocket. Tomatoes wash, halve. Mix vinegar, salt, pepper and sugar. Beat 1 tablespoon of oil down. Mix with tomatoes and rocket.
Arrange the salad on 4 small plates or a large plate. Cut the meat into thin slices. Spread tuna sauce over it and sprinkle with remaining capers
A great starter for guests: roast the meat the day before and prepare the sauce. But only just before serving, arrange with rocket salad to keep it fresh
