Cook the Noodles: Bring a pot of water to boil and cook the rice noodles according to package instructions until al dente. Drain and rinse under cold water to stop the cooking process. Set aside.
Make the Sauce: In a small bowl, whisk together gochujang, soy sauce, sesame oil, honey (or maple syrup), minced garlic, and grated ginger until smooth.
Sauté Vegetables: In a large skillet or wok, heat a drizzle of sesame oil over medium-high heat. Add the sliced bell peppers and snap peas, cooking for about 3–4 minutes until they are tender but still crisp.
Combine Ingredients: Add the cooked noodles to the skillet with the sautéed vegetables. Pour the gochujang sauce over the top and toss everything together until well coated and heated through (about 2 minutes).
Serve: Remove from heat and garnish with chopped green onions and sesame seeds. Add fresh cilantro if desired for extra flavor.
