1Rinse the quinoa under cold water.
In a medium saucepan, bring 2 cups of water to a boil.
Add the quinoa to the boiling water, reduce the heat to low, cover, and simmer for about 15 minutes or until the water is absorbed and the quinoa is tender.
Remove the saucepan from heat and let the quinoa sit, covered, for 5 minutes. Fluff with a fork and let it cool.
While the quinoa is cooling, dice the cucumber, halve the cherry tomatoes, and finely chop the red onion.
In a large bowl, combine the cooled quinoa, cucumber, cherry tomatoes, red onion, and feta cheese.
In a small bowl, whisk together the olive oil, lemon juice, salt, and black pepper.
Pour the dressing over the quinoa mixture and toss to combine.
Serve immediately or refrigerate for later. Enjoy your Vegetable Quinoa Salad!
