Put all ingredients in a food processer.
Pulse until you get a thick thick but pourable batter. Rest for a few minutes until the waffle maker warms up.
Ladle some batter into the maker, let it spread out evenly, then close the lid. Following the manufacturer’s instructions, cook the waffle for a few minutes - it should be golden and crispy.
Make more waffles from the remaining batter. It’s enough for 3 or 4 waffles, depending on your machine.
Serve the waffles immediately with honey and lightly toasted pistachios, or other toppings, spreads, creams of your choice.
