Begin by bringing a large pot of water to a rolling boil. Once boiling, carefully add the rice noodles. Cook according to the package instructions until they are al dente, usually about 4-6 minutes. Drain the noodles in a colander and set them aside to cool.
In a large skillet or wok, place the vegetable oil and heat over medium-high flame until shimmering.
Once the oil is hot, add the sliced red bell pepper, julienned carrots, and minced garlic to the skillet. Stir-fry the mixture for about 3-4 minutes, allowing the vegetables to soften slightly while still retaining some crunch.
Toss in the fresh bean sprouts and finely chopped green onions. Continue to stir-fry for an additional 2 minutes, ensuring they are tender yet remain vibrant and crisp.
In a small mixing bowl, blend the soy sauce, brown sugar, chili paste, and lime juice. Stir the mixture thoroughly until the brown sugar is completely dissolved, creating a well-combined sauce.
Return to the skillet and add the drained rice noodles. Pour the prepared sauce over the noodles and carefully toss everything together, making sure that all the noodles and vegetables are well-coated. Cook for roughly 2 minutes more, stirring gently to heat thoroughly and infuse the flavors.
Divide the vibrant noodle mixture onto serving plates. Finish by garnishing generously with fresh cilantro leaves and a sprinkle of crushed peanuts for an added crunch and flavor contrast.
Notes
Adjust the chili paste according to your spice preference.
