In a non-stick skillet over medium-high heat, heat oil. Trim all visible fat from pork and brown for 3 minutes on each side, depending on thickness of chop. Remove from pan. Add garlic, green pepper and onion to pan and sauté for 1 minute.
Add whole tomatoes, crushing with a spoon. Add remaining ingredients, mix well, reduce heat to low, cover and simmer for about 5 minutes. Return meat to pan and continue simmering, uncovered, for another 15 minutes. Remove from heat and serve over pasta or rice.
