Cut chicken breast and various vegetables (broccoli, carrot, onion, etc.) into bite-sized pieces.
Rinse tofu noodles lightly under running water.
Heat olive oil in a pan and stir-fry the chicken breast over high heat.
When the chicken breast is about half cooked, add the vegetables and stir-fry together.
Once the vegetables are semi-cooked, add the tofu noodles and season with soy sauce, salt, and pepper.
Stir-fry for another 2-3 minutes to blend all the ingredients together and finish.
