Cut chicken breasts into small cubes. 

Heat a deep skillet over medium heat.  Once it is hot, add 3 tbsp of teriyaki sauce, the minced garlic, and the chicken.  When chicken is almost done, add the matchstick carrots and cook together for a few minutes.  

While chicken is cooking, bring a large pot of water to a boil.  Add a few large pinches of salt to the water.  Once the water is boiling, cook the noodles as directed on package. 

When the pasta is done, drain the noodles and add them to the skillet with the chicken and carrots.  Add the rest of the teriyaki sauce and mix together well.  Add the frozen peas and stir in gently. 

Season with black pepper and a little bit of salt, if needed.
