In a medium saucepan, combine quinoa and water. Bring to a boil, then reduce heat to low, cover, and simmer for 15 minutes or until water is absorbed. Fluff with a fork and let cool.

In a small bowl, whisk together olive oil, lemon juice, minced garlic, oregano, salt, and pepper until well combined.

In a large mixing bowl, combine cooled quinoa, cherry tomatoes, cucumber, bell pepper, red onion, feta cheese, and parsley. Drizzle with dressing and toss to combine.

Serve immediately or refrigerate for 30 minutes to allow flavors to meld. Enjoy!
