In a small bowl, whisk together the apple cider vinegar, minced garlic, Italian seasoning, olive oil, salt, black pepper, Dijon mustard, and honey.
Place the pork in a resealable bag and pour the marinade over it. Seal the bag and refrigerate for at least 30 minutes.
Preheat the grill to medium-high heat and lightly oil the grates to prevent sticking.
Remove the pork from the marinade and shake off any excess. Place it on the grill and cook, turning occasionally, until the pork reaches an internal temperature of 140°F.
Remove the pork from the grill, tent loosely with foil, and let it rest until the internal temperature reaches 145°F.
Slice, serve, and enjoy.
Notes
Use an instant-read meat thermometer to make sure that the pork is cooked to a safe temperature before eating. Refrigerate the leftover pork in an airtight container for up to 5 days.
