Heat the chicken and Italian dressing in a skillet over medium-high heat. Season with salt and pepper.
Cook chicken until browned and cooked through, about 5 minutes.
Add pasta and marinara, fill the marinara jar with water and add it to the skillet. Stir lightly.
Bring to a boil, then reduce to a simmer. Cover and cook for 15 minutes until pasta is tender.
Top with Parmesan and mozzarella, cover, and cook for another 2-3 minutes until cheese is melted.
Garnish with basil (optional) and serve. Enjoy!
Notes
The chicken should reach an internal temperature of 165°F. Store in an airtight container in the refrigerator for up to 3 days or freeze for up to 3 months.
