Easy Grilled Italian Chicken

I'm not sure if anyone else does this, but I got this recipe from my mom!! Only requires two ingredients- one bottle of fat free Italian dressing and one package of chicken breasts.
Typically, I buy boneless and skinless. They generally don't hold as much flavor as the chicken breasts with the bones left in and the skin on... But I prefer them.
Use a strainer to get all of the spices out of some of the dressing. Get an injector, inject the chicken with the dressing. Put em all in a bag and pour the rest in a bag. Marinate for at least 30 minutes. Then grill them! I usually use a meat thermometer to check the doneness. I pull them off at 140 F and let them rest for ten minutes. The residual best will cook them the rest of the way through, and having them rest before cutting into them will redistribute the juices so they stay tender. Probably my go to healthy meal, because it's high in protein, low in fat, and still tastes delicious. Not to mention it's cheap and we all know it can be difficult to eat healthy on a budget.
