Toss chickpeas and broccoli in oil, salt and pepper. Add to a sheet pan lined with parchment paper. Bake for 30-35 minutes, until chickpeas are crisp and broccoli is charred.
Add all dressing ingredients to a bowl and mix until fully combined.
Add cooked broccoli and chickpeas to a bowl along with the remaining salad ingredients. Pour over dressing and toss together all ingredients until everything is fully immersed in dressing.
Notes
This makes 5-6 servings of salad depending on whether you are having it with a protein or not.*I recommend using a mandoline to get the celery evenly sliced.
