Wash the lemon and cut into slices. Wash the tomato, cut in half, remove the stalk and cut the tomato into slices. Peel the onion and cut it into slices as well. Drain the olives and artichoke hearts.
Clean and wash the salad, pluck into bite-sized pieces and arrange on a plate with the other ingredients. For the vinaigrette, mix vinegar, sugar, salt and pepper and add 3 tablespoons of oil.
Pour over the lettuce and leave to infuse. Peel garlic and cut into thin slices. Heat the remaining oil in a frying pan. Wash the prawns, dab dry. Fry the garlic and prawns on all sides for about 3 minutes and place on the salad.
Italian flatbread tastes good with it.
