I oven roasted the beets and kohlrabi til they were just tender enough to pass a knife through. I peeled the beets and sliced the kohlrabi in half, scooping out pieces with a melon-baller. The radish was sliced very thin with a sharp knife.
The whipped feta was made by blending the cheese with some heavy cream and milk until completely smooth and then chilling for an hour to firm it up.
