Method:
Place quinoa in fine-mesh strainer and rinse under cold water until water runs clear. Drain quinoa and set aside.
In a large skillet, bring 1/2 cup water to a simmer over medium-high heat. Add carrots and cook about 2 minutes. Add mushrooms, garlic and ginger. Cover and cook until mushrooms are tender and have released their liquid. Uncover and cook 2 to 3 minutes longer or until most liquid has evaporated. Add quinoa and stir 1 minute. Whisk miso into 2 cups water and add to quinoa. Bring to a simmer, then cover and continue simmering until quinoa is almost tender, about 12 minutes. Add peas, cover and continue cooking until quinoa grains are tender and liquid is absorbed, about 5 minutes more. Transfer to a bowl and stir in green onions. Serve immediately.
