Drain the chickpeas into a jug or bowl (keeping the liquid, which you will use later).
Cut the beetroot roughly into cubes, and zest and juice the lemons. Place the chickpeas, beetroot and lemon zest and juice into a blender or food processor.
Peel and crush or grate the garlic cloves and add to the blender, followed by the tahini, paprika and olive oil if you are using it.
Blitz to a smooth paste, then gradually add some of the chickpea liquid until the desired consistency is reached, (I used about half the liquid).
Season generously with salt and pepper to your own taste, (I used about 1 teaspoon salt), and serve.
