Dice the toast. Sauté in 2 tablespoons of oil, remove. Wash meat, dab dry. Fry in 1 tablespoon of oil for about 12 minutes. Clean, wash and cut the salad into strips.
Mix anchovies, egg, 1 pinch of salt, pepper, mustard and lemon juice (all at room temperature!) with a hand blender. Mix in 150 ml oil, dilute with water if necessary. Peel, chop and stir in onion and garlic.
Slice the parmesan, stir in half. Mix with salad. Cut the meat open. Add to salad with croutons and the rest cheese.
