In a large saucepan, heat the olive oil. Add the onion and sauté over medium heat until tender and translucent, about 3-4 minutes.Add the millet, water, cauliflower, garlic and salt. Bring to a boil over high heat, cover and simmer for 25-30 minutes, until the vegetables are soft and the millet is cooked.Remove from the heat. Transfer to a food processor and blend until smooth or mash with a potato masher until desired consistency is achieved. The food processor will make this much smoother.Transfer to a serving bowl and sprinkle with chives, if you like. You can also stir in a little unsalted butter for a creamy finish, but it’s delicious without.
