In a resealable plastic bag, combine garlic pepper, Parmesan cheese, and crushed red pepper. Add the boneless skinless chicken breast tenderloins to the bag, ensuring they are fully coated with the mixture. Seal the bag, then refrigerate for at least 30 minutes.

Place a large nonstick skillet over medium-high heat and lightly spray it with cooking spray. Once hot, add the marinated chicken pieces to the skillet. Let the chicken sear without stirring for about 4 minutes until golden brown, then flip each piece and cook for an additional 2-3 minutes until cooked through.

In a mixing bowl, combine the tomato sauce, remaining garlic pepper, and sugar substitute. Stir the mixture well until evenly blended.

Once the chicken is fully cooked, lower the heat to medium and add the rotini pasta and the prepared tomato sauce to the skillet. Gently toss everything together, ensuring everything is well combined and coated in the flavorful sauce. Let it simmer for about 3-5 minutes.

Serve your Garlic Parmesan Healthy Chicken Pasta with a sprinkling of shredded mozzarella and garnish with freshly chopped parsley or basil. Enjoy!
