Turn on the grill but leave one burner unlit if you don't have a griddle, let the grill reach medium high heat.

Open the package but keep the packaging because it is good to use the leftover marinade to brush the meat.

Then close the grill slices on a hot grill for 2-3 minutes on each side, then move them to an indirect heat for about 10 minutes or until the core temperature has reached 67°C. 

Let the meat rest for 5-10 minutes after cooking, the core temperature will rise by 2-4 degrees. 

It is important that the meat is allowed to rest so that the core temperature reaches 70°C degrees.
