Make small slits all over the pork loin and insert the garlic cloves into the slits. Season generously with pepper (do not salt).
Wrap the pork loin completely with the bacon strips.
Place on a charcoal grill over medium-high heat. Turn every 5 minutes until the bacon is crispy and the pork reaches an internal temperature of 63°C (145°F) when measured at the thickest point.
