Pour dressing over chicken until thoroughly covered. Turn the chicken to be sure to get both sides. Cover and allow to marinate for at least 30 minutes.
Clean potatoes. Cut in one-inch wedges, leaving skin intact. Add olive oil to a large skillet heated over medium-high heat. Add potatoes. Cook for 15 minutes, turning frequently to brown on all sides.
Add Italian dressing, minced garlic, onions, and fresh herbs. Add salt and pepper to taste. Continue to cook until potatoes are cooked all the way through.
