Preheat oven to 375°F / 190°C. Rinse and trim off ends of beets. Wrap in foil and place on a baking sheet and bake until you can easily pierce through the beets with a sharp knife (time depends greatly on size of beets, but around 60 minutes). Remove from oven and peel back a corner of the foil to let some of the steam out. When beets are cool enough to handle, slide the skins off.
Wash kale and spin entirely dry (otherwise the kale will just steam in the oven). Drizzle with a little oil and rub to coat each leaf, sprinkle with salt. When the beets are nearly done, place them on the lower shelf of the oven and put the kale chips on the middle to upper wrack. Bake until crisp – about 15 minutes.
Slice beets into any shape you desire – I chose thin discs to show their interior pattern, but quarters or cubes is fine too. Toss with a little of the dressing and set aside.
To assemble, place a few whole kale leaves on each plate, add dressed beets and a sprinkling of pumpkin seeds if desired. Drizzle remaining dressing over the kale, and add more grated horseradish if you dare. Enjoy.
Whisk all ingredients together.
