Heat 1 tablespoon of olive oil in a large oven-safe skillet or Dutch oven over medium heat.
Add the onions and mushrooms and sauté until tender; add the minced garlic and stir constantly for 45 seconds. Add the mushroom mixture to the stuffing and mix gently then set aside.
Slice pockets into the pork chops by slicing horizontally on the side, and almost through to the other side. Season the pork with sea salt and fresh cracked pepper then stuff with stuffing.
Heat the remaining tablespoon of olive oil in the same Dutch oven over medium-high heat. Sear the pork chop on one side for 5 minutes until golden brown. Flip the chop and place the skillet in the oven for 9-11 minutes or until cooked through.
Remove from the oven and let the meat rest for 3-5 minutes before serving.
