Begin by bringing a generously salted pot of water to a rolling boil. Add the pasta and the chicken bouillon and follow the instructions on the package for cooking time. Before draining, remember to save at least 1/2 cup of the pasta cooking water.
In a bowl, marinate the chicken breast with cajun, onion powder, garlic powder, salt, pepper, paprika and dried parsley.
On a medium high heat, add some olive oil and start cooking the chicken on both sides. After it is done, set it aside.
In the same pan, add some butter, diced onions, diced pepper, tomatoes, garlic and cook them for a bit.
Add some heavy cream, chicken bouillon, Cajun spice, Parmesan cheese and let it simmer for 10 mins.
Add your cooked penne pasta to this sauce and top your pasta with the grilled chicken.
Enjoy while warm!
