Stir together all of the salsa ingredients and set aside in the refrigerator until ready to serve.
Season the tenderloin(s) with salt, freshly ground black pepper. Place pink peppercorns on a hard flat surface and crush with a heavy bottom pan.. Measure out 1 teaspoon of crushed peppercorns and set aside. Sprinkle the remaining peppercorns over the tenderloin(s), and drizzle with a little olive oil. Let sit at room temperature while prepping the grill.
Set up grill for direct cooking over medium-high heat. Brush and oil grate when ready to start cooking. Place pork on the hot oiled grill. Cook for 3 to 5 minutes on each side (four sides) for a total of 14 to 18 minutes or until internal temperature registers a minimum of 140˚F (medium rare) and up to 160˚F (medium).
Remove tenderloin(s) from grill and let rest for 5 minutes before slicing. Slice across the tenderloins on the bias, sprinkle with reserved pink peppercorns, and serve with cherry salsa.
