Add chopped leeks and beets to the baking sheet, drizzle with olive oil and season with salt and pepper. Toss to coat. Then bake for 15-20 minutes or until fragrant and lightly browned. For crispier beets, remove leeks from pan and continue roasting beets for an additional 10-15 minutes (I prefer mine crispier). Set aside.
