Wash the rice thoroughly in several changes of water and drain. In a pot with a lid, boil 525-550 ml ( 2 1/3 cups) of water with a little salt. When it is boiling, add the rice, cover with a lid and simmer until all the water has been absorbed and the rice shows signs of starting to stick to the pot. Do not stir very often so as not to crush the rice. Separately, prepare the marinade for the rice. Boil the vinegar and dissolve the salt and sugar in it. Once the rice is cooked, place it in a large bowl to cool and then mix it with the marinade.
Clean the shrimp well, season with salt and pepper, and dredge in flour, beaten egg and then panko. Then fry in a pan of hot oil until golden brown.
Then, on a sushi rolling mat covered with foil, place the nori sheet, and cover with a thin layer of rice evenly patted over about 3/4 of the surface.
To prevent the rice from sticking to your hands, have a bowl of cold water nearby to wet your fingers each time you take out some rise. It will slide easily and be easier to spread evenly.
Add the shrimp, chopped vegetables, and some finely chopped lettuce greens, inside, then roll the kimbap tightly with the bamboo mat.
After it is formed, keep it still in the rolling mat and press the ends well.
When you have finished rolling the kimbap, slice it with a sharp knife into pieces of about 1 - 1.5 cm (0.3 -1/2 inches) thick. To keep them neat and tidy, wipe the knife blade on a damp cloth before each slice.
