This was a simple. I bought a marinated pork loin from Lundardi’s, and did the following:

On the propane grill:

• about three minutes a side over high heat for a very light sear;
• at the same time, I grilled some fresh sage and chopped fresh rosemary;
• I wrapped the pork loin in foil with olive oil and the rosemary and sage, and set it on the top shelf in the propane barbecue for one hour;

Over charcoal:

• I seared it on all sides over high heat

It was perfectly cooked; fantastic. We served it with white rice and broccoli, grilled over the charcoal.
