Cook the Noodles : Cook the dried egg noodles according to the package instructions. Once cooked, drain, rinse under cold water, and set aside.
Prepare the Chicken : In a bowl, toss the chicken strips with the curry powder, turmeric, garlic powder, and ground ginger to coat them evenly.
Stir-Fry the Chicken : Heat a large non-stick wok or skillet over medium-high heat and spray with cooking oil. Add the seasoned chicken and stir-fry for 4-5 minutes, or until the chicken is cooked through and golden. Remove the chicken from the skillet and set aside.
Cook the Vegetables : Spray the skillet again with cooking oil and add the sliced onion, mushrooms, green and red peppers, and grated carrot. Stir-fry for 3-4 minutes, or until the vegetables are slightly softened but still crisp.
Scramble the Eggs : Push the vegetables to one side of the skillet and pour the beaten eggs into the other side. Allow the eggs to set for 30 seconds, then scramble and mix them into the vegetables.
Combine Everything : Return the cooked chicken to the skillet and toss with the vegetables and eggs. Add the cooked noodles, soy sauce, rice vinegar, and granulated sweetener. Stir-fry for 2-3 minutes, ensuring everything is evenly coated with the sauce.
Garnish and Serve : Remove from heat and sprinkle the dish with the finely sliced spring onions. Serve hot and enjoy your flavorful Chicken Singapore Noodles!
