Cook the Ramen noodles as per the directions on the package. When done, drain and set aside.
Heat a wok or large skillet over medium-high heat until it's very hot—almost smoking. Add 1 TBSP of sesame oil, then add the shrimp. Give the shrimp a few tosses and move them around so they don't stick. Cook until the shrimp are pink, opaque, and curled into a C. This should only take 3-5 minutes, depending on the size of te shrimp. When done, transfer the shrimp to a bowl and set aside.
Add another TBSP of sesame oil to the wok or skillet. Add all of the vegetables and give them a few tosses. Let them cook for about 5-7 minutes, or until tender but still crisp. The mushrooms will soak up a lot of the oil, so add more as needed. You can also add a few splashes of water to a drying pan to keep things from drying out and sticking.
With a spatula, move the vegetables to the side of the wok. Add the lightly beaten eggs. The eggs will start cooking as soon as they hit the pan. Treat it like you would a scrambled egg, stirring it occasionally, until it breaks off into fluffy chunks, for about 1 minute.
Add the shrimp to the wok and toss in the Ramen noodles. Remove the wok from the heat and drizzle the stir-fry over all of the ingredients. Carefully toss everything until you have even coverage. Taste, and if needed, add a bit more sesame oil and/or sambal oelek.
Garnish with toasted sesame seeds or chili flakes.
