What kind of potatoes should I make with this pork loin?

Bought a pork loin marinaded with Italian Style Herbs which I am asuming are garlic, basil, thyme, etc. Was thinking of garlic mashed or rosemary roasted, but I'm afraid those flavors are too similar to the spices in the pork. What other potato dish would be good to balance it out? Not sure about veg yet, but probably zuchinni or spinach...
