Preheat oven to 400F. Place beets and garlic on a medium piece of aluminum foil; drizzle with olive oil and wrap the foil around the beets and garlic. Roast for 1 hour, or until the beets are fork tender. Allow to cool and peel off the skin.

Place beets, garlic and all remaining ingredients in a food processor and blend until smooth. Pour hummus into a bowl and garnish with a drizzle of olive oil, pine nuts and a sprig of rosemary.
