Combine orange juice and zest, Dijon, extra virgin olive oil, thyme, salt and pepper in a jug or similar. Stir or whisk until well combined. Place chops in a bowl or container and pour over marinade. Turn chops to coat. Cover and marinate in the fridge about 2 hours.
Heat olive oil and butter in a large frying pan over high heat. Add chops and cook to your liking. I like mine slightly under but you may prefer them well done. Serve with your choice of side or sides.
