I made this for my folks for Mother's Day 2012 - very delicious. I made this without salt since my dad is on a salt restricted diet ...you could use garlic salt and onion salt.
Served with roasted broccoli and oven fries.
Place boneless pork loin on large cutting board or platter; brush oil over all sides. Set aside. Meanwhile, stir together dry rub seasoning. Rub over pork to cover.
Preheat grill on high.
Place pork loin over medium high heat (about 400 degrees F.) gas grill. Cook for 5 minutes on each side to brown. Move pork to area on grill over indirect heat. Cook, covered for 25 - 30 minutes with the lid down or until internal temperature reaches 150 degrees F. On gas grill, move pork to one side of grill; turn off the gas directly under the pork. Leave the rest of the grill on medium heat.
I used a gas grill with 3 burners. Cooked the loins on the back burner of the gas grill after they were seared... turned back burner to OFF
Turned the middle burner to Low
Turned the front burner to Med High
