Wrap each mozzarella cheese stick with a piece of prosciutto. Set aside.
Slice a pocket into the side of each chicken breast horizontally. Insert 2-3 prosciutto wrapped mozzarella sticks inside and secure with toothpicks.
In a large skillet add the olive oil and butter over medium heat. Season each chicken breast on both sides with salt and pepper. Brown on each side for several minutes. Add the white wine and cover immediately. Turn heat to low and cook for 10 minutes or until internal temperature is 165°F.
Remove toothpicks and serve with topped with a spoonful of pesto and Parmesan cheese. Spoon pan juices over all.

Notes
I typically make this using four chicken breasts.
The other day I saw these already made up in the deli section of a market, I think it was Trader Joe's. They look perfect!
