Marinate the chicken thighs in the Italian dressing for at least 30 minutes in the refrigerator. I use a Ziploc bag for this and turn them over at least once.TIP: You can put chicken in marinade in the morning, and it will be ready to cook at dinner time in the evening.
Drain the marinade from the chicken. Discard the used marinade.
Toss the chicken with the 2 packs of dry Italian dressing mix to cover well.
Place the coated chicken onto a hot griddle on the stovetop over medium-high heat. (You can cook the chicken in a skillet if you like) Cook the chicken for about 7-8 minutes per side. Cook time will depend on how thick your chicken thighs are. Use a meat thermometer to determine if they are done. Chicken is done when it reaches 165°.
While the chicken is cooking, heat the Pasta Sauce in a saucepan. It doesn't need to be boiling. It just needs to be hot when you top the chicken and linguine with it.
Boil the noodles according to the package directions and then drain.
Layer each serving dish with noodles, followed by the cooked chicken, and then spoon the sauce on top. Sprinkle with the grated Parmesan cheese.
