Wipe out the skillet, add the olive oil and heat until shimmering. Add the stuffed chicken and cook over high heat until golden on the bottom, about 4 minutes. Turn the cutlets and cook for 2 minutes longer. Add the wine and stock to the skillet, cover and bake in the oven for about 12 minutes, or until the chicken is cooked through. Transfer the chicken to a platter and remove the toothpicks. Cover with foil and keep warm.
