For the vinaigrette, mix the vinegar with 1/2 teaspoon salt, a pressed garlic clove, sugar, mustard and 4 tablespoons oil. Mix the onion, tomatoes and rocket in a bowl together with the vinaigrette.
Heat 3 tablespoons of olive oil in a pan. Sweat the chopped garlic and the chilli pepper in it. Fry the prawns in it over medium heat for 2 minutes. Salt, pepper and sprinkle with parsley.
Arrange the salad on a plate and distribute the warm prawns on top. Sprinkle with freshly ground black pepper. Roughly slice the parmesan and pour over it with the sprouts and chives. Finally, decorate with a little balsamic cream.
This goes well with ciabatta slices fried in olive oil, rubbed with garlic and lightly salted.
