Put the peanut butter, soy sauce, Sriracha sauce and the juice of one lime in a small bowl and stir until a smooth paste is formed.

Quarter the cucumber lengthways. Cut the individual quarters lengthways into thin strips. Cook and drain the glass noodles according to the instructions on the packet. Pluck the mint leaves from the stems, wash and dry them. Separate a few leaves of the lettuce, wash, dry and cut into pieces that are a little as long as the cucumber strips.

Pour water into a large bowl. Put a sheet of rice dough in each for about 15-20 seconds and let it soak. Remove and place 1-2 pieces of lettuce in the middle of the lower third. Place 2 Gruken strips and a couple of rice noodles on top. Drape a few mint leaves just above it. Likewise 2-3 prawns. Now fold up the lower end of the rice dough sheet. Then fold in the sides. Roll up tightly from the bottom up. Dip with the peanut sauce if you like. Good Appetite!
