Using scissors, cut the soaked noodles roughly in half so it’s easier to mix them with the veggies. Place all your prepped ingredients by the stove, ready to go.
Place a wok or large nonstick skillet on high heat and pour in just enough oil to coat the bottom. Once the oil is very hot, lay the shrimp down in one layer and let them sear without moving them until at least halfway cooked, about 2 minutes. Flip and cook on the other side until they are done. Turn off the heat and transfer the shrimp to a bowl, leaving all the oil and any juices behind.
Add a bit more oil to the pan if needed so that you have about 3 tbsp. (Having enough oil is important to make sure that the noodles don’t clump together.)
Add the garlic and shallots and turn the heat to medium. Stir until the shallots are translucent, about 2 minutes.
Turn the heat up to the hottest it can go and add the noodles and sauce (see note #3). Toss together until most of the sauce has been absorbed. At this point it will look like there aren’t nearly enough noodles, but don’t panic, the dish will bulk up with the veggies and proteins.
Push the noodles to one side of the pan to create space for the eggs, then break the eggs into the pan. Scramble slightly just to break the yolks, then move the noodles on top of the eggs and let the eggs continue to cook for another 30 to 45 seconds, until they are mostly cooked. Flip the noodles and then toss to break up the eggs.
Give the noodles a quick taste to check their doneness. If they’re too chewy, add a splash of water and keep tossing for 1 minute or so to allow the water to absorb.
Add the shrimp back to the pan, along with any juices, and toss to mix. Turn off the heat and add the bean sprouts, garlic chives and half of the peanuts. Use tongs to mix just until everything is evenly distributed. Plate immediately – you want the bean sprouts to be as fresh as possible, so don’t let them linger in the hot pan unnecessarily.
Top with the remaining peanuts and serve with wedges of lime. Add some roasted chili flakes for heat, if desired.
