Preheat oven to 400°F (200°C). If using raw beets, peel, cube, and roast for 30–40 minutes until soft. Let cool. For puree: Blend roasted beets with a small amount of water or oil until smooth.
In a saucepan, gently heat olive oil with cumin and coriander for 5 minutes on low. Remove from heat and let infuse for several minutes. Strain if desired.
Lightly toast bread slices. Rub with cut garlic and brush with olive oil.
Cut into small cubes and place in a shallow dish. Pour water or broth over bread and let soak 5–10 minutes until soft and moist, yet holding shape. Test texture as needed.
Toss cubed beets with cumin & coriander oil, salt, and optional balsamic vinegar. Crumble goat cheese finely (Level 5) or use soft chunks (Level 6). Plate with pregelled crostini and garnish with fresh herbs.
