In a large pot, bring water to a boil. Add the rice noodles and cook according to package instructions until al dente. Drain and rinse with cold water to stop cooking. Set aside.
In a small bowl, whisk together the gochujang, honey (or maple syrup), soy sauce, sesame oil, rice vinegar, minced garlic, and grated ginger until smooth. Adjust the sweetness or spiciness by adding more honey or gochujang if desired.
In a large skillet or wok, heat a teaspoon of oil over medium-high heat. Add the sliced bell peppers, carrot, and snap peas. Stir-fry for about 3-4 minutes until the vegetables are tender-crisp.
Add the cooked noodles to the skillet with the vegetables. Pour the gochujang sauce over the noodles and toss everything together until the noodles are well coated and heated through. Cook for an additional 2-3 minutes.
Remove from heat and stir in the sliced green onions. Transfer the noodles to a serving dish and garnish with sesame seeds and fresh cilantro.
Notes
Adjust the sweetness or spiciness to your preference.
