Spray a roasting rack and shallow roasting pan with nonstick spray or grease lightly with some oil.
Remove skin from chicken, rinse well, and pat dry.
Using a pastry brush, coat both sides of each piece of chicken well with the salad dressing (there should be a little left over).
Set breasts, meaty sides up, onto the sprayed roasting rack and sprinkle with rosemary.
If you like, season to taste with a little seasoned salt& pepper.
Sprinkle bread crumbs on top of the chicken (or you can dump the crumbs in a dish and roll the chicken in the crumbs if you like more coating-this may require addtl crumbs).
Bake 20 minutes, then flip pieces over using a pair of tongs and brush with some more salad dressing (if you chose to roll your chicken in the crumbs, then skip the extra salad dressing).
Bake another 40 minutes or until cooked through.
Cook time will vary based on the actual weight of your chicken pieces-allow 15 minutes per pound plus 10-15 extra minutes to calculate the total cooking time (this includes before and after flipping the chicken).
