Using a sharp knife, score pork chops in a crosshatch pattern on both sides. Place in a baking dish just large enough to hold a single layer. In a small, nonreactive bowl, stir together 1 cup juice, 1/4 cup oil, thyme leaves, and rosemary; pour over pork chops to coat. Cover with plastic wrap, and let marinate refrigerated at least 4 hours or up to overnight.
Remove pork chops from marinade and pat dry; discard marinade. Heat remaining 2 tablespoons oil in a large skillet over medium-high heat. Season pork chops with salt and pepper. Transfer to skillet, and cook, turning once, until lightly browned, about 6 minutes per side. Reduce heat to medium; add remaining 1/2 cup blood orange juice. Cover, and cook until pork is cooked through, about 5 minutes. Serve immediately with green beans and spinach, if desired.
