Combine water and salt in a large pot and bring to a boil over high heat. Meanwhile, rinse the quinoa. Add the quinoa and stir briefly. When it returns to a boil, reduce the heat to low and simmer gently until quinoa absorbs the liquid and grains are tender, about 10 to 15 minutes.
When quinoa is ready, stir in remaining ingredients until well combined. Taste, adjust seasoning, as needed, and serve.
