Preheat the oven at 400F. Chop about 1/4" from the top of the garlic head, exposing the cloves
Add the garlic head to a sheet of aluminum paper + the beets, and drizzle 2 teaspoons of olive oil over both
Cover with the aluminum and bake for 25-30 minutes, or until the garlic and beets are tender
Allow to cool, remove the garlic cloves from their skins, and add them to a food processor, with the beets, the rest of the olive oil, chickpeas, tahini, and lemon juice
