Start by bringing 2 cups of water to a rolling boil in a medium saucepan.
Once the water is boiling, add the rinsed quinoa. Lower the heat to a gentle simmer, cover the pan, and cook for approximately 15 minutes, or until the quinoa grains are fluffy and all the water has been absorbed.
After cooking, remove the saucepan from the heat and allow the quinoa to cool to room temperature, exposing it to air to speed up the cooling process.
In a large mixing bowl, combine the diced cucumber, diced tomatoes, and chopped red onion. Mix gently to incorporate the flavors.
Once the quinoa has cooled, add it to the bowl with the vegetables, mixing thoroughly to ensure an even distribution.
Fold in the finely chopped fresh parsley and mint leaves, gently stirring to combine all ingredients harmoniously.
In a separate small bowl, whisk together the olive oil, freshly squeezed lemon juice, and a pinch of salt and pepper, to create a vibrant dressing.
Drizzle the prepared dressing over the quinoa salad mixture and gently toss to coat all ingredients evenly with the flavorful dressing.
Taste the salad and adjust seasoning with additional salt, pepper, or lemon juice as needed to achieve your preferred flavor.
Cover the salad with plastic wrap or a lid and refrigerate it for at least 30 minutes before serving. This resting time allows the flavors to meld beautifully.
Notes
For an eye-catching display, serve the salad in a large, colorful bowl. Garnish with extra fresh mint leaves and lemon wedges on the side.
