In a large mixing bowl, combine the cooked quinoa, diced red and green capsicums, grated carrot, grated beetroot, and chopped parsley. Toss everything together gently to distribute the ingredients evenly.
In a small bowl, whisk together the extra virgin olive oil, lemon juice, dried oregano, salt, and pepper. Give it a taste and adjust the seasoning according to your preference.
Pour the olive oil lemon dressing over the salad. Gently toss to coat all the ingredients with the dressing. The vibrant colors will come alive even more!
Taste the salad and add more salt and pepper if needed. Remember that the flavors will meld as the salad sits. Allow the salad to rest for about 10-15 minutes before serving to let the flavors marry.
