Start by roasting your beets and garlic - preheat the oven to 350 degrees F. Toss the beets and garlic in olive oil, then roast in the oven for 30 minutes, until beets are tender. (Time will depend on how large/small you chopped your beets.)
When done, take out of the oven and let cool.
Once garlic cloves have cooled down a little, add them to your food processor BY THEMSELVES and process on their own - it will do the mincing for you. Then add beets, chickpeas, and all other ingredients, and process on high until hummus has reached the desired consistency.
When done, scoop hummus into a bowl and garnish with fresh rosemary and almonds, if desired.
