Prepare the Beets:
Preheat your oven to 400°F (200°C).
Wash and scrub the beets. Trim the ends but leave the skins on.
Wrap each beet individually in aluminum foil and place them on a baking sheet.
Roast for 45-60 minutes, or until a knife slides easily into the center.
Let the beets cool slightly, then peel off the skins using a paper towel or your hands. Slice or dice the beets as desired.
Alternative method: Boil the beets in a pot of salted water for 30-40 minutes, then peel and slice.
Toast the Nuts:
In a dry skillet over medium heat, toast the walnuts or pecans for 2-3 minutes, stirring frequently, until fragrant. Set aside.
