Add chicken breasts to a large ziplock bag. Pour Italian dressing over the chicken, seal the bag and place it into the refrigerator. Marinate the chicken for at least 15 minutes.
Preheat the oven to 400°F. Grease a baking dish and place chicken breasts into the dish, pouring the Italian dressing from the bag over the chicken.
Top the chicken evenly with breadcrumbs and lightly spray with oil. Bake for 40-45 minutes, or until chicken is cooked through. For a more crispy topping, broil the chicken for an additional minute, watching closely so it doesn't burn.

If you don't have time to marinate, you can just pour it over the chicken and bake immediately.
Instead of baked chicken, you can remove the chicken from marinade and cook on the grill.
The breadcrumb topping is optional. You can also mix the breadcrumbs with a few tablespoons of parmesan cheese.
