Cut chicken breast in half, lengthwise, then season generously with cajun seasoning blend. Spray a large skillet with nonstick cooking spray.
Over medium high heat, cook chicken for 4-5 minutes on each side or until cooked through. Remove from skillet and set aside.
Using the same skillet over medium heat, add the oil from the sun-dried tomatoes (only the oil) and diced onions. Cook until onions are tender (approximately 5 minutes).
Add minced garlic, sun-dried tomatoes, and a splash of broth, stirring constantly for 4-5 minutes.
Stir in the evaporated milk, dried basil, cajun seasoning, red pepper flakes and cut up chicken breast. Bring to a simmer. **If too thick, add small amounts of milk until desired consistency is achieved.
Turn heat to low and add shredded cheeses. Once melted, remove skillet from heat.
Toss sauce with cooked pasta. Slowly pour in HOT pasta water until desired sauce consistency.
Right before serving, stir in freshly chopped parsley.
