Recipe adapted from Kitchen Confidante
5 tsp minced garlic
2 tbsp balsamic vinegar
2 1/2 tsp kosher salt
1/2 tsp pepper
2 tbsp olive oil
2 pork tenderloins
Stir together all the ingredients (except for the pork) to create a paste. Coat each pork tenderloin with the paste and allow to marinate for at least one hour- preferably 24 hours.
Preheat grill to medium high heat and grill each of the four sides for 5 minutes. The internal temperature should be 160 degrees, if it isn't keep on grilling until it reaches that point.
Let the tenderloins rest for ~5-10 minutes before slicing.
