Butterfly the chicken breasts then lay flat, cover with plastic wrap, and pound thin using the flat side of a meat mallet.
Season each breast with salt and pepper, brush each chicken breast with 1 teaspoon of dijon mustard then lay down 1 piece of ham, and a few pieces of cheese.
Fold the sides of the chicken breast then roll.
Bread the chicken by rolling them in flower, dipping them in eggwash, and then rolling in breadcrumbs.
Heat a large skillet over medium heat. Add 1 tablespoon of butter, and 1 tablespoon oil into the pan.
Add the chicken into the pan and brown on all sides.
Once the chicken is browned put it in a 400°F oven for 15-20 miutes or until the chicken is cooked through (165°F). Let cool for 3-4 minutes, then serve.
