Steam beets for 15 minutes or so until they are soft enough to cut, but not mushy
While beets are steaming, combine apple cider vinegar, white sugar and salt in a saucepan and simmer until the sugar is completely dissolved
Allow beets to cool and slice into roughly ½" slices. Put into jars or other sealable containers, add salt, peppercorns, cloves and mustard seeds and cover with vinegar mixture. Allow to cool in refrigerator for at least 4 hours
Lay down a bed of greens, top with thinly-sliced watermelon radish, pomegranate arils, sliced goat cheese and pickled beets
