Rinse pork tenderloin and pat dry with paper towels.
Lay tenderloin on a cookie sheet and drizzle with olive oil.
Reserve a tablespoon of spice mixture. Sprinkle pork evenly with remaining spice mixture and pat down to adhere.
Place pork on grill for 7 minutes with lid closed. Turn over and cook for another 6 minutes on high with lid closed. Turn down a bit if your spices are burning. Then turn off grill and leave pork on with lid shut for 5 minutes. Check internal temperature for 150°.
Prepare salsa. Place diced peaches, 1 tablespoon of reserved spice mix, honey and mint in a bowl and toss gently. Serve alongside your pork.
