4-5 lb pork tenderloin
Preheat oven to 500 degrees. Rinse pork and pat dry with paper towel. Rub olive oil over whole tenderloin. Pat all sides with grill rub. Place on roasting rack in shallow roasting pan. (If you do not have a rack, add a splash of water to the bottom of the roasting pan.) Place pork in oven and roast for 10 minutes, leaving temperature on 500. Do NOT open the oven during this 10 minute period to ensure a crispy coating. Then turn the oven down to 350 degrees and continue cooking pork 40 minutes more, or until done. Cover the pork with Foil and let "rest" for 15 minutes before cutting, to ensure pork stays juicy. Slice and serve.

Note: I have to be careful when selecting my grill seasonings as I have 1 kid who doesn't like "spicy"... but he practically baptizes his pork in ketchup when I make this, so it's all good. :)
