In a large saucepan, cook and stir quinoa over medium-high heat 3-5 minutes or until toasted. Add water; bring to a boil. Reduce heat; simmer, covered, 12-15 minutes or until liquid is absorbed. Transfer to a large bowl. Cool slightly.
In a small bowl, whisk oil, lemon zest, lemon juice, garlic, parsley, mint and salt. Add vegetables to quinoa; drizzle with dressing and toss to combine. Cover and refrigerate until ready to serve.
