1 5-to-6-ounce package cellophane noodles
1/3 cup soy sauce
5 tablespoons sesame oil
1 clove garlic, minced
1/3 cup brown sugar
1 1/2 tablespoons apple cider vinegar
12 ounces skirt steak, sliced 1/4 inch thick against the grain
1 yellow onion, cut into 1/4-inch wedges
10 ounces shiitake mushrooms, stems removed
1 cup shredded carrots (from about 3 carrots)
6 cups baby spinach (about 10 ounces)
Soak the noodles in warm water to soften, 5 to 10 minutes, then drain and snip into pieces with kitchen shears.
Meanwhile, combine the soy sauce, 3 tablespoons sesame oil, the garlic, brown sugar and vinegar in a bowl. Put the beef in another bowl and toss with 2 tablespoons of the soy sauce mixture.
Heat 2 teaspoons sesame oil in a large nonstick skillet over high heat. Add the onion and 1 teaspoon salt and stir-fry 2 minutes. Add the beef and stir-fry until just cooked through. Transfer to a bowl.
Rinse and wipe out the skillet, return to the heat and add 2 teaspoons sesame oil. Add the mushrooms and carrots; stir-fry 3 minutes. Add the noodles and 2 tablespoons of the soy sauce mixture and stir-fry 1 minute; add 1/3 cup water and cook until the noodles are just tender, 3 minutes. Transfer to the bowl with the beef.
Wipe out the skillet, return to the heat and add the remaining 2 teaspoons sesame oil. Add the spinach and the remaining soy sauce mixture and cook, stirring, 1 minute. Add to the beef and toss.
