Thoroughly coat beets with oil then salt and pepper them.
(If you're using different types of beets and want to retain color integrity, roast each variety on a separate pan. It will keep color from bleeding onto the lighter beets.)
Roast until beets are tender, about 20 minutes.
Remove from oven and allow to cool.
(See recipe for dressing and nuts to finish salad)
Sprinkle with feta cheese to finish.
