Glazed Pork Tenderloin

Preheat oven to 400º and grease a large baking sheet. Arrange tenderloin on the pan with orange slices under the edges and season generously with salt and pepper. In a medium saucepan, bring orange juice, brown sugar, garlic, and Italian seasoning to a boil, then reduce heat and simmer until reduced by half, 5 to 7 minutes. Pour mixture over pork. Bake for 25 minutes, then switch to broil and cook 5 minutes more. Slice and serve immediately.
