Cut the salmon into 2 centimeter cubes, drizzle with lemon juice and refrigerate for an hour. Let the oil get hot in a pan, fry the cubes of salmon, drained on paper towels, season with salt and pepper and fry for another 3-4 minutes. Finally fry the shrimp and the spring onion cut into rings for about a minute. Mix the ingredients for the marinade. Toss the cleaned and spun dry salad in the marinade and distribute on the plates. Pour the salmon and shrimp over the salad, garnish with the halved cocktail tomatoes and the chopped egg.
