Mix egg thoroughly with mustard, oregano,salt & pepper to taste. In separate bowl, combine panko and parmesan. Dredge chops lightly in flour, dip both sides in egg mix and then in panko mix. Place on rack to settle coating. Heat a cast iron frying pan with oil over medium heat & heat just until a bread crumb sizzles in the oil. DON'T OVERHEAT. Cook chops till golden brown, turning once. Approximately 5-7 minutes per side.
Spinach & arugula should be rinsed and dried. Cut cherry tomatoes in halves or quarters. Combine with garlic, olive oil, lemon juice, salt & pepper. Blend & set aside.
When chops are done, place on dinner plate. Add the greens to the tomato/lemon and stir to coat. Spoon the salad mix over the chops and serve
