In a medium saucepan, combine the rinsed quinoa and vegetable broth (or water). Bring to a boil over medium-high heat.
Once boiling, reduce the heat to low, cover, and let simmer for about 15 minutes, or until the quinoa is fluffy and all the liquid has been absorbed. Remove from heat and let it sit covered for 5 minutes. Fluff with a fork.
In a large bowl, combine the halved cherry tomatoes, diced cucumber, diced red bell pepper, chopped red onion, and cooked chickpeas.
Add the cooked quinoa to the vegetable mixture and gently toss until well incorporated.
Stir in the sliced Kalamata olives, crumbled feta cheese, and chopped parsley.
In a small bowl, whisk together the olive oil, lemon juice, salt, and pepper to create a dressing. Drizzle over the quinoa mixture and toss gently to coat.
Taste and adjust seasoning with additional salt, pepper, or lemon juice if needed.
Notes
Serve in deep dishes or wide bowls, and garnish with lemon wedges and parsley for a vibrant look.
