While quinoa is cooking, drain and rinse the garbanzo beans, chop spinach, tomatoes, bell pepper, cucumber, dill, green onions and olives and place all the chopped veggies and beans in a large mixing bowl. Stir to combine.
Once quinoa is cooked, remove lid to cool before adding to the salad. Once cooled (about 15 minutes), add the quinoa to the salad.
Pour the dressing over the salad just before serving and stir to incorporate.
