Cook the Noodles: In a large pot, bring salted water to a rolling boil. Add noodles and cook according to package directions, usually around 8-10 minutes. Drain and rinse under cool water. Set aside.

Whisk the Sauce: In a mixing bowl, combine gochujang, soy sauce, brown sugar, tahini, sesame oil, and 2 tbsp of water. Blend until smooth. Set aside.

Heat the Oil: Place a large wok over medium-high heat and pour in the vegetable oil. Heat for about 1 minute until shimmering.

Sauté the Vegetables: Add chopped broccoli rabe and minced garlic to the hot oil. Season with salt and pepper, stirring frequently for about 2 minutes until crisp-tender.

Combine with the Sauce: Pour the reserved sauce over the sautéed vegetables. Stir well and cook for an additional 2 minutes until the sauce thickens slightly.

Mix in the Noodles: Add cooked noodles and fresh basil to the wok. Toss everything together for about 1 minute until well coated.

Serve and Garnish: Transfer to serving bowls, top with sesame seeds, basil leaves, and lime wedges. Serve warm.
