Cook pasta in boiling water until it is al dente according to the package directions. Meanwhile, prepare the chicken strips according to the package instructions.
Heat olive oil in a large saucepan over medium heat. Add onions and cook until tender. Add garlic and cook 30 seconds more.
Pour in chicken broth and cook 3 minutes or until reduced by half. Stir in the marinara and Alfredo sauces.
Bring the mixture to a boil, reduce heat and simmer on medium-low for 5 minutes.
Toss sauce together with cooked pasta. Top with chicken strips and parmesan cheese.
Notes
Nutrition calculated without chicken strips.
Add a pop of freshness with chopped fresh basil leaves or parsley as a garnish.
If you prefer a spicier kick, sprinkle some red pepper flakes into the tomato sauce while it's simmering.
Don't overcook the pasta! Cook it al dente, which means it should still have a slight bite to it.
Consider adding some sautéed vegetables like bell peppers, mushrooms, or spinach to the creamy tomato pasta.
