Combine all of the Marinated Tomato ingredients a medium bowl, set aside until ready to serve. This can be done up to 3 hours ahead, let sit at room temperature. For the cutlets, in three shallow bowls - put panko, eggs and flour in each bowl. Dip the cutlets in the flour, then the egg and then the panko crumbs. Salt and pepper cutlets. Preheat the oven to 250 degrees. In a large frying pan, melt the butter and oil over medium-heat. When this mixture is foamy, put the slices in the hot oil. Do not crowd the slices. Turn the slices over as they begin to brown, 3 - 4 minutes. When the cutlets are golden on each side, place cutlets on a baking sheet and keep warm in the oven while you cook the remaining cutlets. You can add a bit more butter and oil to frying pan, if necessary. Serve warm with the marinated tomatoes.
