Cook the couscous or quinoa according to package directions.
In the meantime, prepare the vegetables and drain and rinse the can of chickpeas.
In a jar or bowl, combine all dressing ingredients until smooth. Now assemble. This works great to make salad jars by dispersing the ingredients evenly between 4 mason jars.
Alternatively, assemble in a bowl, by adding the quinoa, vegetables, chickpeas, vegan feta, pistachios and dressing. Toss and store in the fridge for up to four days.
