Cook the quinoa by placing the quinoa and 2 cups of water (470ml) in a pan, and bring to a boil. Turn down the heat and simmer until the water is absorbed, about 10-15 minutes.
While the quinoa is cooking, you can make the dressing by adding all of the dressing ingredients to your blender, and blending until creamy and smooth.
When the quinoa is cooked, place in a large mixing bowl and add the red onion, pepper, black beans, red cabbage and cilantro.
Pour the dressing over the salad and stir until everything is combined.
Serve cold or at room temperature.
