Mix together mustard, vinegar, honey, garlic, salt and two tablespoons of olive oil. Chop the fresh rosemary and add 1 teaspoon to the marinade. Once mixed, add the cubes of fresh pork and toss to combine. Cover and refrigerate for at least 1 hour, preferably overnight.
Preheat your grill to medium-high. Remove the pieces of pork from the marinade and place on skewers, leaving a little space between each so they cook evenly. Wash and cut the peaches into quarters. Place the peaches on skewers and drizzle with remaining olive oil. Season with salt and pepper and remaining rosemary.
Preheat your grill to medium-high and cook pork 7-8 min on each side, until done. Grill peaches 4-5 mins on each side. Arrange on a platter and serve.
