Place the zucchini in a flour sack towel or cheesecloth and wring it out over the sink to remove as much liquid as possible.
In a food processor fitted with the steel blade, process the macadamia nuts until coarsely ground. (Do not over-process or you will create macadamia nut butter, which, while delicious, is not what we’re going for here.) Add the zucchini and process to combine. Add the remaining ingredients one at a time, processing to combine after each addition until everything has been added and the hummus is creamy.
Serve with fresh vegetables.
Notes
To roast the garlic, cut off the top of the head of garlic. Drizzle with olive oil and sprinkle with a pinch of salt. Wrap in aluminum foil and roast in a 400ºF oven for 35-45 minutes. When cool enough to handle, squeeze out the garlic cloves.
