This pork loin recipe is a spicy and tangy dish that is perfect for a summer barbecue. The chipotle and lime marinade adds a smoky and zesty touch to the pork. Start by blending chipotle peppers, lime juice, garlic, salt, and pepper in the food processor. Rub the mixture all over the pork loin and let it marinate for at least an hour. Preheat the grill to medium-high heat and grill the pork loin for about 20 minutes on each side or until the internal temperature reaches 145°F. Let it rest for 10 minutes before slicing and serving.
