Fill water in a pot on heavy heat and heavily salt.
Cut chicken breast into diced bite-sized pieces. Place in a bowl and season with cajun seasoning, garlic powder, and Italian seasoning. Mix well to incorporate.
Heat 2 tablespoons of oil in a large skillet on medium high heat. Once hot enough add in chicken and cook for 10 minutes or until cooked through, stirring occasionally. Take the chicken out of the pan and set aside.
By now the water should be boiling. Add in the pasta and cook til al dente.
In the same skillet on medium heat add the onions and peppers. Cook for 5 minutes constantly stirring. If sticking to the pan add in 1 tablespoon of olive oil.
Add in the can of diced tomatoes to the pan. Season with garlic powder and red pepper chili flakes. I added about 1 tablespoon of the red pepper chili flakes because I like spice. Cook for 1 minute.
Turn heat to medium high. Add the heavy cream to the pan, chicken broth, and cheese. Cook for a few minutes and constantly stir. Add the chicken back into the pan and the pasta and mix well with the sauce.
Take off the heat. I like to let it sit for a few minutes in the sauce for it to set and become super creamy.
Plate and sprinkle some fresh parsley on top if you’d like. Enjoy!
