Cook the Quinoa according to the directions and then fluff it with a fork and let it cool.
In a bowl, whisk together the olive oil, apple cider vinegar, dijon mustard, honey, garlic, salt and dill. Let this sit while the quinoa cools and you prepare the rest of the salad.
In a large bowl, add in the arugula, sliced cucumber, chickpeas, and quinoa. Add the dressing and toss to coat. Add on the feta cheese and lightly toss. Serve immediately.
Notes
Only use as much dressing as you like. Save the extra for later by putting it in the fridge. If making the salad in advance, wait to add the dressing until right before serving.
