Clean and wash the asparagus and mangetouts. Cut asparagus diagonally into pieces and cook in boiling salted water for about 8 minutes until al dente. Add sugar snap peas in the last 2-3 minutes and cook with them.
Drain the vegetables and let them cool down. Wash the tomatoes, drain and cut in half. Clean the frisée salad, wash and drain. Roast sesame seeds in a pan without fat and let them cool down. Peel and finely dice the shallots.
Mix lime juice, vinegar, soy sauce, shallots, salt, pepper and sugar. Whip sesame and sunflower oil into the mixture. Line 4 plates halfway with the mangetouts. Mix the cherry tomatoes, asparagus and frisée salad with the vinaigrette and arrange on the mangetouts.
Shrimps, except for the tail, loosen from the shell and remove the intestines. Heat garlic butter in a pan and fry the king prawns in it for 3-4 minutes. Season with salt and pepper and spread on the salad plates.
Sprinkle with sesame seeds and serve immediately.
