In a small pot over medium-high heat, bring the quinoa and 1⁄2 cup water to a boil. Reduce
the heat to low, cover, and simmer for 15 minutes. Remove from the heat and let it sit for 10 minutes with the lid on.
Meanwhile, make the macadamia nut ricotta: In a food processor, blend the macadamia nuts, 1⁄4 cup of water, nutmeg, lemon juice, and salt until smooth. Set aside.
In a large bowl, toss to combine the spinach, citrus, blackberries, red onion, avocado, almonds, and quinoa.
Drizzle the olive oil and lemon juice over the top. Toss to combine once more. Add salt and pepper to taste.
Divide between salad plates or bowls and top with 1 to 2 dollops of macadamia nut ricotta.
