Cook the noodles according to the instructions on the package.
Heat one tablespoon of sesame oil in a wok over high heat. Add the sliced steak and sear on all sides for 3-4 minutes, until browned but still a little pink in the center. Remove from the wok and set aside.
Add the remaining tablespoon of sesame oil to the wok and bring up to a high heat. Reduce the heat to medium-high right before adding the vegetables. Start by sautéing the red onions and carrots until tender, about 1-2 minutes, then add the garlic (plain) and ginger. Sauté until fragrant, about another 3-4 minutes.
Toss in the pineapple, red pepper, and black garlic. Stir until softened, about 2-3 minutes. Add the baby corn last and cook for another minute.
In a small bowl, whisk together the soy sauce, spicy honey, rice vinegar, red pepper flakes, the remaining garlic (plain), and ginger.
Add the cooked noodles to the wok, then pour in the sauce. Gently stir until the sauce coats everything evenly.
Add the beef back to the wok. Season with salt and pepper to taste. Stir until the beef is heated through but not overcooking, about 3-5 more minutes.
Serve garnished with chopped chives and microgreens, as desired. Enjoy!
