Cut the avocados in half, remove the seeds. Spread salmon slices on the avocado halves, pressing the salmon into the hollows of the seeds. Place the avocado halves on the hollows of a muffin baking tray for a better stand. Beat the eggs and slide them into the avocado wells. Season with salt and pepper. Bake in the preheated oven (electric cooker: 150 °C/circulating air: 125 °C/gas: see manufacturer) for approx. 20 minutes.
Whisk vinegar, salt and pepper. Add the oil. Peel and finely dice the shallot and stir into the vinaigrette. Sort the salad, wash and shake dry. Wash the dill, shake dry and pluck flags from the stems. Mix salad leaves, dill and vinaigrette. Arrange baked avocados with salad.
Place the avocado halves on a muffin tray or on four cups for gratinating.
