In a medium saucepan, bring the water and salt to a boil. Add pre-rinsed quinoa. Cook over medium heat for 10-12 minutes, just until the quinoa is tender. Once done, fluff with a fork and set aside.
While the quinoa cooks, peel and chop the vegetables.
Add the cooked quinoa to a large bowl. Pour in the lemon juice, olive oil and garlic and stir just to combine. Add in the vegetables and sprinkle with salt and pepper. Toss and serve.
This salad is perfect served at room temperature or cooled.
