Mix together the mustard, vegetable oil, and herbs in a small bowl.
Coat one side of the pork chops liberally with this mixture. Sprinkle black pepper onto the mustard-coated side.
Place chops mustard-side down on a plate covered with wax paper or parchment paper. Repeat mustard coating and seasoning with pepper on second side of chops.
Refrigerate for at least 1 ½ hours (can prepare to this point one day ahead), covered loosely.
Bring chops to room temperature for 30 minutes before cooking.
Mix together flour and breadcrumbs in shallow bowl. Season with salt and a bit more black pepper.
Dredge pork chops in flour mixture, shaking to remove excess flour.
Heat vegetable oil in large skillet over medium high heat. Carefully place pork chops into oil, being careful not to crowd the skillet. Cook until browned, about 5 minutes, and turn carefully.
Complete browning on second side, about 5 more minutes. Carefully remove from skillet.
