Whisk all the ingredients together in a bowl. Rinse the pork, pat it dry, and drop it into a ziplock with the sauce. Leave it sit for an hour or overnight.

Grill the pork on the barbecue, turning every 6 to 7 minutes. Total cooking time usually takes about 20 minutes total. Boil the remaining marinade to use as a sauce, if desired. Allow to rest for a few minutes, then slice and serve.
