Cook the Noodles: Begin by boiling water in a large pot. Add the rice noodles and cook for 5-7 minutes, or until they are soft but still slightly chewy. Drain and rinse under cold water to stop the cooking process. Set aside.
Prepare the Sauce: In a small bowl, mix together gochujang, soy sauce, sesame oil, honey (or maple syrup), and sesame seeds, stirring until smooth. Set aside.
Sauté Vegetables: In a large skillet or wok, heat vegetable oil over medium heat. Add minced garlic and sauté for about 30 seconds until fragrant. Toss in the shredded carrots and bell pepper, and stir-fry for 2-3 minutes until slightly softened.
Combine Noodles and Sauce: Add the cooked noodles to the skillet along with the gochujang sauce. Toss everything together to ensure the noodles and vegetables are well coated in the spicy sauce. Stir-fry for another 2-3 minutes until heated through.
Garnish and Serve: Remove from heat and toss in chopped green onions. Serve the noodles hot, garnished with fresh cilantro (if using) and lime wedges on the side for an extra burst of flavor.
