Hard boil eggs. Then quench, peel and let them cool down.
Wash the basil. Put something aside for garnishing, chop the rest very finely. Halve the eggs. Carefully remove the egg yolk and possibly pass it through a sieve. Mix the egg yolks, 3 tbsp. mayonnaise, tomato paste and basil.
Meanwhile cut the meat open and cover half of the toasts with it. Add pear slices, tomatoes and the rest of the toast. Pin the sandwich with rosemary and possibly cut in half diagonally.
For the sauce, drain the tuna and puree finely with milk, 2-3 tbsp. mayonnaise and lemon juice. Stir in capers. Season sauce with salt and pepper.
Wash the salad and shake dry. Arrange on a plate with the Kasseleraufschnitt. Place the eggs on top. Spread the tuna sauce over the smoked pork loin. Garnish with basil. Serve with baguette.
