Defrost the mussels if necessary. Wash and drain the salad. Cut or cut out 1 thaler of approx. 6 cm Ø from each brioche slice. Wash the mussels and pat them dry well.
Cut the ham slices in half crosswise, fry them crisply in a pan without fat and take them out. Heat 1 tbsp. butter in a frying pan. Fry the briochetaler in it from both sides until golden brown and take it out.
Wipe the pan with kitchen paper.
Heat 1 tablespoon each of oil and butter in the pan. Fry the mussels for 1 1/2 minutes on each side and push them to the edge of the pan. Beat the eggs, carefully put them into the pan and fry them over a low heat until they are fried.
Season everything with salt.
Place 1 briochette, 2 pieces of ham, a few salad leaves, 1 mussel and 1 egg on top of each other on plates. Sprinkle with pepper and garnish with the rest of the salad.
