Marinate the crabs in soy sauce and pepper. Prepare instant noodles according to the instructions on the packet. Clean and chop the vegetables.
Heat the oil in the wok and fry the vegetables in it for about 5 minutes. Then add the crabs and boiled noodles - fry for another 3 minutes. Add the sweet and sour sauce and fry for another 2 minutes. You can of course also make the sweet and sour sauce yourself (recipe in the CK).
