Start by rinsing the quinoa under cold water using a fine sieve.
In a pot, add the quinoa and 2 cups of water. Bring it to a boil, then reduce the heat, cover, and simmer for about 15 minutes until quinoa is cooked.
Once done, fluff it with a fork and let it cool to room temperature.
In a large mixing bowl, toss in the cooled quinoa, chopped mint leaves, and fresh parsley.
Add the diced cucumber, halved cherry tomatoes, and finely chopped red onion to the mix.
Drizzle olive oil and lemon juice over the salad.
Sprinkle the lemon zest, salt, and pepper, then give everything a gentle toss.
If you're adding feta, crumble it in now.
Mix well, ensuring the flavors are well combined.
