Preheat your oven to 400°F. In an oven-safe skillet with high sides, add the oil and preheat it over medium-high heat.
Wrap a slice of prosciutto around each piece of chicken and secure it with a toothpick. Add each piece of wrapped chicken to the hot skillet (top-side down) and cook for one minute. Flip each piece and season the tops with the granulated garlic and Italian seasoning; sear about a minute on each side.
