Step 1
Prepare the yaki-soba noodles according to the package directions. Do not use a seasoning packing if included. For fresh noodles, just add them to boiling water for 1-2 minutes until they separate and become tender. Dried noodles usually need to be boiled for 4-5 minutes.

Heat the olive oil over medium high heat, Add the onion and celery and cook for 3-4 minutes. Add the cabbage and cook for 2 minutes until just tender. Add the noodles and the sauce. Cook for 2-3 minutes, stirring often. Taste and season if needed with additional soy sauce or pepper.
