Drain and rinse the chickpeas. Put the garlic clove, chickpeas, 3 tablespoons oil, peanut butter, lemon juice, salt, and cumin into a food processor and blitz to a knobbly puree. Add 1/4 cup of the Greek yogurt and process again; if the hummus is still very thick, add another 1–2 tablespoons yogurt and the same of oil. (This will often depend on the chickpeas, as different sorts make the hummus thicker or not.) Taste for seasoning, adding more lemon juice and salt if you feel it needs it. On serving, mix the chopped peanuts with the paprika and sprinkle on top if you wish, and put an array of bits and pieces to eat with or dip in, as you see fit.
