Once you have done that, it should look like a flat large piece of chicken chop.
The next thing to do is to coat and marinade the chicken. I used my favorite thing ever...Shake N Bake! It's just to easy to use and yummy to eat (if there is no Shake N Bake available in your area, just mix some Italian breadcrumbs, Parmesan cheese, garlic powder, salt and pepper to taste). Pour some Shake N Bake on a plate.
I know that the correct way to Shake N Bake is put the chicken pieces into a plastic bag, pour in some Shake N Bake and shake it around to coat the chicken pieces. That method works well with small pieces of chicken but not large ones like this. So, just pour it on a plate and coat the chicken well on both sides.
Pour some Marinara/Pasta Sauce into a baking dish. Make sure it covers the entire bottom of the dish.
Place the coated chicken thighs (skin side facing upwards) on the Marinara sauce.
Once it's cooked, remove it from the oven.
Put a slice of cheese on top of each chicken thigh. I used Swiss cheese but your can pretty much used any type of cheese. Mozzarella and Provolone taste pretty good too. Pop it back into the oven for about 8 minutes or until the cheese melts.
There you go! A very simple and yummy tray of Chicken Parmigiana.
I served the Chicken Parmigiana on top a bed of Butter & Herb Spaghetti. To make the spaghetti, just cook the spaghetti til al dente and toss it in butter and herbs. Quick and simple ;P
