Rinse shrimps briefly and defrost at room temperature for 1-1 1/2 hours. For the vinaigrette, whisk 2 tablespoons of water, vinegar, salt, pepper and honey. Add 3 tablespoons of oil drop by drop.
Peel and finely dice the onion and stir into the vinaigrette. Wash and halve the tomatoes. Clean the rocket, wash and spin dry. Wash lemons hot and grate them dry. Cut into thin slices.
Cut the rolls into 32 cubes. Peel the shrimps, except for the tail fin, and remove the intestines. Wash the shrimps and pat them dry. Put the prawns, bread and lemon slices alternately on the skewers.
Wash thyme and oregano, shake dry, pluck leaves from the stalks and chop. Peel garlic and press it through a garlic press. Mix herbs, garlic and 4 tablespoons of oil. Season with salt.
Lightly grease the skewers with it. Carefully grill on the hot grill for approx. 8 minutes, turning over (it is better to use a grill tray; grilling time increases by approx. twice as much). Arrange the salad on plates, drizzle with vinaigrette.
Add skewers.
