Beets are best when cooked in season i.e. June to December in the US.
Method:
Rub beets generously with olive oil; loosely wrap individually in aluminum foil with a crushed garlic. Heat oven to 400°C. Roast beets until cooked.
Remove from oven, open foil. Peel skin of beets. Cut into large chunks. Remove the cheese of your choice from freezer. Slice cheese and place evenly over beets.
Spread walnuts around, sprinkle olive oil over contents and return to oven until cheese chunks melt. Remove dish, add the vinaigrette. Toss and serve.
