Preheat the oven to 425 degrees and line a baking sheet with parchment paper.
Add the chickpeas, oil & dry seasonings to the baking sheet and toss to coat. Place in the oven for 10 minutes, toss and place back in the oven for 5-10 minutes, or until crispy. Remove from the oven and allow to cool slightly.
Meanwhile prepare the honey mustard dressing (linked above). Set aside.
To assemble, add the arugula and 1/2 the dressing to a large mixing bowl. Toss until coated. Top with the chickpeas, feta, pickled onions & parsley.
Spoon onto plates and top with the remaining dressing.

Notes
You could sub the vegan feta for avocado.
This is best served right away - if making ahead of time, wait to add the dressing until right before serving.
