Roast the beets. Preheat oven to 400 degrees. Toss beets with a little oil, salt, pepper and water, put in a deep pan, cover with foil and put beets in oven.
Cook for about 1 hour. Check to see if the beets are cooked by sticking a knife in or squeezing. There should be some give, but not too much.
Allow beets to cool until they are easy to handle. Then peel. The skin should come off easily with the help of a paring knife. Try scraping with the knife before resorting to cutting off the skin. If the skin is moist enough, you may even be able to rub off the skin with your fingers.
Cut the beets in a shape you prefer. For our presentation, I would go with slices or wedges.
Make the Mousse:
Mix the blue cheese, cream cheese, salt, and pepper in a food processor until smooth.
In a separate bowl, whip the cream until it forms soft peaks. You can do this either by hand or in a mixer.
Fold the cream into the cheese mixture.
Make the vinaigrette: Place all ingredients except for oil into a blender. Turn on high speed and drizzle in the oil until an emulsion forms.
Arrange the beets in the center of the plate. Put the mousse in a pastry bag with a wide tip. Pipe the mousse on top of or in the middle of the beets. You can do layers if you prefer. garnish with Micro greens and drizzle the vinaigrette around the plate and a little over the top.Serve imediately.
