Boil noodles according to package and set aside in big mixing bowl.
Heat 1 tbsp evoo over medium heat and add your chicken. Sauté until done. Set aside when done.
In same skillet add 1 tbsp evoo, bell peppers, onion, and garlic. Sauté 3-4 minutes. *I add the garlic in at the end because if you add it too soon it may burn.
Add mushrooms and tomatoes. Sauté 3-4 minutes or until all veggies are tender.
Reduce heat to medium low and add in your cajun seasoning, chicken broth, and slurry of milk, cream cheese, and flour. *side note: a slurry is where you mix your milk, cream cheese, and flour in a blender or with a fork until it mixes together
Stir up the veggies, broth, and slurry really good and add the chicken and noodles to the mix and stir really well.
