Grilled Pork tenderloin w/Blood Orange Sauce

This recipe comes from Gourmet magazine, I changed it up by using blood oranges since I had some in the fridge. The taste was sensational and the prep work and grilling were simple. I used a 1 pound tenderloin, they used two 3/4 pound ones.

Pat tenderloin dry and rub with 1/2 tablespoon olive oil, 1/2 tsp. salt and 1/2 tsp. Italian seasonings.
