Preheat oven to 400°.
Cut potatoes in halves or thirds depending upon their size.
Place potatoes in a glass 8x8 inch pan.
Pour olive oil, rosemary, salt and pepper over potatoes and stir.
Place in oven and cook for about 20-30 minutes until fork tender.
While cooking, stir the potatoes every 10 minutes so they don't stick to the bottom of the pan.
Remove from oven and toss with the chives or dill.
Place in a shallow bowl and top with the parmesan cheese.
