Prepare the noodles according to package instructions, drain, rinse, and set aside. Undercook the noodles slightly as they will cook more with the other veggies in the pan or wok.
Make your sauce. Add all the ingredients for the sauce to a measuring jug and whisk together until well mixed. Ensure the sauce is smooth and the peanut butter is mixed well with all ingredients. Set aside.
Heat a large pan or wok over medium heat.
Add the sesame oil, sliced red bell pepper, and grated carrot to the pan or wok and flash fry to soften the veggies slightly.
Pour the sauce over the veggies and mix in. Cook until the sauce is heated through.
Add the noodles, peanuts, green onion, and cilantro and gently toss together until the noodles are well coated and heated through.
Serve in bowls topped with a sprinkle of crushed peanuts, chopped cilantro, and lime wedges on the side.
