Pork Tenderloin and Roasted Vegetables

First I cover the pork with a rub made of mustard, garlic, fresh herbs, salt and pepper.  Let it sit while preparing the vegetables.  I like potatoes, carrots, celery and onions.  Fennel is also really good roasted.  Simply salt, pepper, and olive oil.  Preheat the oven to 425 and roast uncovered for about an hour.  Take the pork out to sit, stir the vegetables and roast them until they are nicely browned and caramelized.  Slice the pork and enjoy!
