Steep the kale in hot water in a large bowl until it turns slightly brighter, 1 to 2 minutes. Remove and pat dry.
In a small bowl, combine the vinegar and a pinch of salt and freshly ground pepper. While whisking, slowly drizzle in the olive oil.
Pour half the dressing over the kale in a large bowl. Massage the kale leaves with your hands. Add the quinoa, tomatoes and more dressing and toss together with 2 spoons. Mix in the goat cheese and pine nuts. Transfer the salad to a serving dish. Allow to sit for 20 minutes before serving.
