To cook beets, place them in a medium saucepan. Fill the saucepan with water until the beets are covered. Bring to a boil, then lower the heat to a simmer. Cover and simmer until the beets are cooked through, about 30 minutes. Peel the beets under cold running water and cut each into 6 or 8 wedges. Alternatively, place the beets in a large microwave-safe bowl. Add 1 cup of water. Cover with plastic wrap and cook on high power until tender, about 15 minutes.
