In a small bowl whisk together all the sauce ingredients and set aside until needed.
Preheat a large skillet over medium heat, add a light drizzle of olive oil and saute the onion until it starts to get some color.
Add the Beyond Beef and using a flat end wooden spoon break it up into small pieces. Cook until the edges start to crisp up. Push it to the side and add the bok choy and scallions, toss around and cook until wilted but still bright green in color. (If the bok choy is on the bigger side feel free to chop it up first).
Push everything in the pan to the sides and lightly drizzle some oil in the center. Add the garlic and ginger and cook for a few seconds until fragrant but taking care not to burn it. Give everything a good stir to combine. Add the sauce then let it come to a simmer and bubble once or twice. Remove from heat.
Meanwhile bring a pot of salted water to a boil and cook the noodles according to the directions on the package. Reserve one cup pf the cooking pasta water. DO NOT overcook them, drain them while still al dente, usually shortly after they all untangle from the nest. Rinse with cold water to stop the cooking process.
Add the cooked ramen noodles to the skillet with the the rest of the ingredients and carefully toss to coat well in the sauce. Add a little bit of the reserved cooking water from the noodles to stretch out the sauce if needed and desired.
Serve hot garnished with fresh cilantro, scallions and some red chili flakes for heat.
