Mix the garlic pepper, parmesan cheese, and crushed red pepper in a resealable bag or container. Set aside. (Photo includes both marinade options.)
Cut the chicken breasts into bite size pieces before adding to the resealable container. Shake or stir until fully coated. Refrigerate for at least 30 minutes, but the longer the better.
Once the chicken has marinated, heat a large skillet over medium high heat with nonstick cooking spray.
When the skillet is hot (water drops should sizzle), add the chicken and spread evenly in the pan. Leave untouched for 4 minutes before flipping. Cook another 2-3 minutes after flipping. Make sure you don't have any oddly shaped or large pieces of chicken with pink remaining before reducing the heat to low.
While the chicken cooks, microwave the Ready Pasta and mix the tomato sauce with the garlic pepper, sweetener, and crushed red pepper in a bowl.
Add the pasta and tomato sauce to the cooked chicken and stir. Simmer for a few minutes until the sauce is completely warm and everything is uniformly mixed.
Remove from the heat and top with optional shredded mozzarella before serving.
