Combine the garlic and rosemary. Using a mortar and pestle, grind the ingredients until a paste-like consistency is achieved.

Combine the garlic-rosemary mixture with olive oil, salt, and pepper. Mix well.

Rub the mixture all over the pork tenderloin. Let it stand for 30 minutes to 1 hour.

Grill the pork tenderloin for about 5 to 7 minutes per quarter of a side. This means that we will rotate the meat 4 times.

Let the meat rest for 10 minutes. Slice.

Transfer to a serving plate.

Serve. Share and enjoy!
