Cook Penne Pasta per package directions. Set aside.
Rinse the chicken in water and put in a large resealable bag. Add the cajun seasoning and shake to coat thoroughly.
In a large skillet, melt 2 tablespoons of butter over medium heat. Turn the chicken occasionally to create the perfect crispy, golden brown layer and cook the chicken all the way through (at least 165 degrees fahrenheit). Make sure to check with a knife to make sure it is no longer pink.
When the chicken is almost done, in a saucepan combine the heavy cream, 2 Tbs butter, lemon pepper, salt, black pepper, and garlic powder. When the cream mixture begins to bubble, add the pasta and remove from heat stirring well.
Once chicken is cooked, cut thin strips on cutting board. We use Chicken Tenderloins so we don't have to slice the chicken
Spoon the pasta onto a plate and top chicken, diced tomatoes and parmesan. Sprinkle with more cajun seasoning if desired! Best when served with a side of Texas garlic toast.
