How to Make It
Preheat the oven to 350°. On a rimmed baking sheet, drizzle the cauliflower with 1 tablespoon of the olive oil, season with salt and toss to coat. Roast for about 15 minutes, stirring occasionally, until tender and golden brown. Let cool.
Meanwhile, bring 2 medium saucepans of lightly salted water to a simmer. Cook the red quinoa and white quinoa separately over moderate heat until tender, 12 to 15 minutes. Drain and rinse under cold running water. Drain well.
If popping sorghum, heat the vegetable oil in a medium, heavy pot until almost smoking. Add the sorghum, cover and cook over moderately high heat, shaking the pot occasionally, until the popping has almost stopped; pour into a bowl and season with salt.
In a large bowl, combine the cauliflower, red and white quinoa, almonds, chives, rice vinegar and the remaining 1/4 cup of olive oil. Season with salt and toss well. Transfer the salad to plates, top with the popped sorghum and serve.
Both unpopped and popped sorghum are available at amazon.com.
