* Spread the herbs over the meat on all sides. 
        * Cover uniformly the pork roast with the prosciutto slices.
        * Tie the pork roast with a kitchen string.
        * Place the olive oil in a saute pan large enough to contain the meat. Turn heat to medium. When the oil is hot transfer the meat to the pan.
        * Brown the meat uniformly turning it on all sides.
        * Add the butter the orange juice and the chopped vegetables.
        * Stir, cover the pot and cook on medium low for about  45 minutes. Turn the meat occasionally. Add a little broth if necessary. When the meat is done, set aside the gravy and vegetables, and let the meat cool to room temperature.
        * Place the butter in a large skillet on medium heat. When the butter starts foaming add the orange slices. Sauté briefly for 1 or 2 minutes, turning on both sides.
        * Slice the meat like in a fan, without separating the slices.
        * Transfer the meat in a oven-proof serving dish. Add the gravy with the vegetables on top and around the meat.
        * Cut the orange slices in half. Insert the orange slices among the meat slices. Place briefly back in the oven covered with aluminum foil, to warm the meat before serving.
