Transfer the pork chops to a large, resealable bag.
Pour the marinade into the bag and gently massage the chops so that each one is covered with the marinade.
Set the bag into a large bowl (in case there’s a leak) and let the chops marinate for 30 minutes.
If you plan to marinate for a longer period of time, set the bowl into the refrigerator.
When ready to cook, heat the olive oil in a large skillet, over medium-high heat, remove the pork from the bag and gently shake off the excess marinade.
Fry the pork chops for 4 to 5 minutes per side.
The internal temperature of the pork should be 145°F.
Once cooked, remove from the skillet and set aside.
Pour the leftover marinade into the skillet and crank up the heat to high.

When the pork is plated, serve the thickened marinade as a sauce.
