Roasted Fingerling Potatoes with Olive Oil and Rosemary

Steam halved fingerlings (unless they are small and can roast on their own.)  When they are softer than al dente, remove from the steamer (either microwaved or stovetop) and mix with olive oil, a bit of butter and chopped rosemary leaves. Top with freshly ground sea salt and pepper.  Put them in a roasting pan and roast for about 20 minutes on 350 degrees next to your main entree.
