Rinse the chicken breast fillet under cold water and leave in the piece.
Wash, clean and chop the vegetables and prepare them separately. Drain the bamboo shoots in a sieve and cut into small pieces if necessary. Soak or cook the dried mushrooms according to the instructions on the packet; cut into small pieces. Prepare glass noodles according to the package instructions, cut to bite-size length with scissors and set aside. Prepare the vegetable stock.
