Start by prepping the chicken. Slice the chicken breasts thinly, ensuring uniform pieces for even cooking.
Prepare the vegetables. Julienne the bell peppers and carrots and slice the snow peas diagonally.
Get the noodles ready. Cook the noodles according to package instructions. Drain and set aside.
Time for the stir-fry magic! Heat the peanut oil in a large skillet or wok over medium-high heat. Once hot, toss in the chicken slices. Stir-fry for 5 minutes or until they start to brown.
Bring in the veggies. Add bell peppers, carrots, and snow peas to the wok. Continue stir-frying for another 5 minutes.
Pour in the flavors. Add the satay sauce, soy sauce, and red chili flakes. Ensure all ingredients are well-coated.
Integrate the noodles. Fold the cooked noodles into the wok, mixing well with the chicken and veggies. Stir-fry for another 3-4 minutes until everything is hot and well combined.
