In a medium saucepan over high heat, bring water to a boil. Add quinoa and reduce heat to
medium. Cover and simmer until water is absorbed and quinoa is softened, about 15 minutes.
Remove from heat. Fluff with a fork, then add cranberries on top. Cover and let steam 5 minutes.
Meanwhile, place kale in a large bowl; season with 1 teaspoon salt. Massage kale with your
hands to combine, about 1 minute. Add quinoa, cranberries, apples, onion, pecans, and feta to
kale and toss to combine.
In a small bowl, whisk mustard, oil, honey, lemon juice, and red pepper flakes; season with salt
and black pepper.
Pour dressing over salad and toss to combine
