Rinse the quinoa under cold water.

Combine quinoa and water in a pot, bring to a boil, then reduce to a simmer, cover, and cook for about 15 minutes or until the water is absorbed.

In a large bowl, combine the cooked quinoa, roasted broccoli, chopped spinach, and green onion.

Drizzle with olive oil and lemon juice, then add the chopped pistachios and crumbled feta cheese.

Season with salt and black pepper to taste, and toss gently to combine.
