In a small bowl or jar, whisk together the olive oil, orange juice, lemon juice, honey, salt, and pepper. Set aside.
In a large bowl, combine the kale, olive oil, lemon juice, and salt. Massage the kale with your hands until the kale softens, about 2 minutes.
Add the cooked quinoa, oranges, avocado, mint, pistachios, and feta cheese. Gently toss. Drizzle citrus dressing over the salad and gently toss again. Serve.
Note-blood oranges or clementines are also good in this salad. You could even throw in some grapefruit. This salad is best the day it is made.
