===========

Instructions:

1. Slice beef into thin strips. Combine the rest of the ingredients and let marinate for 30 minutes to 1 hour.
   
2. Cover noodles with very hot water and let soak till softened, about 25-30 minutes.
   
3. For the sauce, whisk all ingredients together and set aside.
   
4. Heat a large skillet to medium-high heat and add 1 tablespoon oil. Add beef in a single layer and let cook undisturbed for 2-3 minutes. Flip and sear the other side for another 3-4 minutes until cooked through. Transfer to a bowl.
   
5. Add remaining tablespoon of oil, shallot, garlic, and a pinch of salt to the skillet. Cook over medium until shallot is soft and browned. Add in the egg and cook till scrambled. (If adding frozen or raw veggies, do so now.)
   
6. Drain the rice noodles and add them to the skillet. Turn heat to medium high and add the sauce, tossing to combine till noodles are well coated.
   
7. Add in beef and any accumulated juices, bean sprouts, peanuts, and half the scallions. Continue to toss and cook till noodles are tender.
   
8. Plate up and top with remaining scallions, peanuts, cilantro, and a squeeze of lime.

Notes:

– Make sure your noodles are tender before adding them to your skillet, but if you find they still need some more cooking time, add 2 tablespoons of water to the skillet and cook till they're tender.

– Heat level can be adjusted per preference. I find that these measurements add just the right balance of spice.
