Roasted Beets
Most vegetables can be prepared with little more than olive oil and salt, but few are as rewarding as beets, which can be stunningly delicious when done this way. One key is to bake them—which dries out their flesh a little bit and concentrates their flavor—rather than boil them. (Think of the difference between a baked and a boiled potato.) It takes some time, but it is easy and reduces staining. Other vegetables you can prepare this way: carrots or parsnips (peel before roasting), turnips or rutabagas; cooking time will vary.
