1Bring the quinoa and water to a boil in a saucepan over high heat. Reduce heat to medium-low, cover, and simmer until the quinoa is tender, and the water has been absorbed, about 15 to 20 minutes. Spread into a mixing bowl, and refrigerate until cold.
2Once the quinoa has chilled, gently stir in the tomatoes, cucumber, and onion. Season with lime juice, cumin, salt, and pepper; stir to combine. Divide the spinach leaves onto salad plates, and top with the quinoa salad. Garnish with the avocado slices to serve.

Cook's Note
Be sure to rinse the quinoa thoroughly before cooking as there is a bitter coating on the grains. Regular quinoa can be used in place of the red quinoa (they taste the same). Red quinoa is usually found in the Organic section of most grocers or also in bulk food type stores.
