Wash the meat, dab dry and season with salt. Heat 1 tablespoon of oil in a large frying pan. Fry the meat for about 10 minutes while turning. Shortly before the end of the frying time, season with paprika and pepper.
Wrap meat in foil and let it rest.
Meanwhile, prepare the pasta in boiling salted water according to the instructions on the packet. Cut toast into cubes of about 1 cm. Wash the rosemary and shake dry. Press on a clove of garlic. Place bread cubes with garlic and rosemary sprigs on the fat pan of the oven.
Sprinkle with 3 tablespoons of oil. Sprinkle with salt and mix briefly with your hands. Roast in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: see manufacturer) for approx. 8 minutes until golden brown.
Drain the pasta and let it drain. Clean, wash and dry the salad. Cut into pieces. Wash tomatoes, grate dry and cut in half. Mix sour cream, mustard, salad cream, stock, lemon juice and sugar.
Season to taste with salt and pepper. Remove meat from the foil and cut into thin slices. Remove crôutons from the oven.
