Begin by rinsing the quinoa under cold running water in a fine mesh strainer. This step is crucial for removing any bitterness. After rinsing, allow it to drain completely.
In a medium saucepan, combine the rinsed quinoa with your choice of vegetable broth or water. Bring this mixture to a vigorous boil. Once boiling, lower the heat to a gentle simmer. Cover the saucepan and allow the quinoa to cook for about 15 minutes, or until the grains are fluffy and all the liquid has been absorbed. After cooking, remove the saucepan from heat and let the quinoa sit, covered, for an additional 5 minutes to steam. Fluff with a fork and set aside to cool slightly.
While the quinoa is cooling, take a large mixing bowl and add the diced cucumber, diced bell pepper, halved cherry tomatoes, finely chopped red onion, chopped parsley, and chopped mint. Toss the vegetables gently to combine them.
Once cooled, add the prepared quinoa to the bowl of vegetables.
For the dressing, in a small bowl or jar, whisk together the lemon zest, freshly squeezed lemon juice, extra virgin olive oil, and a pinch of salt and pepper. Blend until well combined.
Drizzle the dressing over the quinoa salad mixture, and toss everything together gently to ensure the salad is evenly coated.
If you like, sprinkle crumbled feta cheese on top of the salad right before serving for an extra burst of flavor.
Taste the salad and adjust the seasoning by adding more salt, pepper, or lemon juice according to your preference.
Notes
For an elegant presentation, serve in a large bowl or individual dishes, garnished with fresh herbs or a lemon wedge.
