Prepare the Noodles: Cook the noodles according to the package instructions. Place the wide rice noodles in a large bowl and cover them with boiling water. Let them soak for about 10 minutes or until tender but not fully cooked. Drain in a colander and rinse under cold running water. Set aside. (Don’t let them sit for too long: no more than 10 minutes.)
Prepare Chinese Broccoli: Wash your Chinese broccoli and cut off the tough ends of the stalk. Cut the leaves from the stems. Then cut the stem into diagonal slices.
Make Pad See Ew Sauce: Mix all the sauce ingredients in a small mixing bow. Stir until the sugar is completely dissolved. Set aside.
Cook Beef: Heat a large skillet or wok over high heat. Add a tablespoon of oil. Once hot, add beef slices, and saute for about 3-5 minutes until it's nicely browned. Remove the beef from the pan. Leave the oil in the pan.
Stir-fry vegetables: In the same pan, add minced garlic and stir-fry for about 30 seconds until fragrant. Add Chinese broccoli and stir-fry for 2-3 minutes until they start to become tender.
Scramble eggs: Push the vegetables to one side. Add the eggs to the pan and scramble using a wooden spoon. Once the eggs are mostly cooked, mix them with the Chinese broccoli. Remove from the pan and set aside.
Stir-fry rice noodles: Add the rest of the oil to the pan. Once hot, add the well-drained wide rice noodles to get pan. Stir fry for about 2 minutes, so that they are nicely caramelized.
Combine and toss: Pour the sauce over the noodles and toss them together. Add back the cooked beef, Chinese broccoli, and scrambled eggs to the pan.
Taste and adjust the seasoning. Garnish with green onions. Serve immediately and enjoy!
