Heat the oil in a skillet over medium high heat. Add the sliced mushrooms & a pinch of pepper and sear until browned on both sides.
Lower the heat to medium and add the garlic, ginger & whites of the green onions. Cook down for 1 minute. Add in the noodles & soyaki sauce and toss until the noodles are cooked through and coated - add more soyaki sauce if needed.
To finish, top the noodles with the remaining green onion, sesame oil and a drizzle of chili onion crunch. Add to bowls and enjoy!

Notes
The noodles come in a pouch and are pretty stuck together. I like to gently loosen them up with my hands before adding them to the pan.
If you don't have a Trader Joe's, sub the noodles with fresh udon (or any other cooked noodle of your choice) and use any chili oil to finish.
Bulk this up with plant protein - stir-fry some tofu cubes before searing the mushrooms or add in some shelled edamame.
