Cook or prepare the noodles according to package directions. I had udon noodles that did not require boiling but I did rinse them with hot water to simply help loosen them up. Follow the directions for whichever type of noodles you decide to use.
Heat 2 tbsp of oil in a large wok or pot over medium high heat. Once the oil is hot, add the shallots and stir until they become soft.
Next, add the mushrooms and cook until the mushrooms are for just about tender but not too soft. Reduce the heat to medium/low, add the garlic, ginger, bok choy, and stir until garlic is fragrant and bok choy starts to slightly wilt.
Add the noodles, sauce, sesame seeds and stir until well combined and noodles are heated through.
Serve hot and fresh!!
