Begin with the cashew cheese by draining soaked cashews and placing into the bowl of a food processor along with garlic and salt. Pulse until combined. Slowly add almond milk and continue processing for another 1-2 minutes or until mixture is smooth. Set aside.
For the beet mixture, remove greens and root ends from beets. Dispose of root ends, set greens aside and place beets in a medium-size pot of water. Bring to a boil over high heat and cook for 20-25 minutes, or until tender when pierced with a fork. Drain and rinse beets with cold water; set aside.
Meanwhile, rinse beet greens thoroughly and chop coarsely. Bring a small pot of water to a boil over high heat and add greens, boiling for 5 minutes. Remove from heat, drain and rinse with cold water. Press out as much liquid as possible; set aside.
Remove peels from boiled beets and discard. Chop beets and add to a large bowl along with remaining beet mixture ingredients. Mix to combine.
Spread cashew cheese in the bottom of a wide, shallow dish. Top with beet mixture and beet greens, and serve with baguette slices.
