Wash the meat and dab dry. Heat 1 tablespoon of oil in a large, coated pan. Fry the meat on both sides for 1-2 minutes at high heat. Season with salt and pepper and remove.
Peel and finely dice the onion and garlic. Drain the capers. Add 1 tablespoon of oil to the pan and heat again. Sauté the onion and garlic in it until transparent. Add tomato paste and sweat for 1-2 minutes.
Deglaze with tomatoes and tomato juice, bring to the boil. Wash the rosemary, dab dry and put something aside for garnishing. Cut anchovies in half. Add 3/4 of the capers, rosemary and anchovies to the sauce and simmer for about 3 minutes.
Take the rosemary out of the sauce. Add the meat and warm it up for about 2 minutes. Season to taste with salt, pepper and sugar. Sprinkle with remaining capers and garnish with remaining rosemary. Serve with fresh ciabatta bread.
