Prep your onions: mix your apple cider vinegar, water, salt and sugar together. Put your onions in a mason jar or glass container, and pour the vinegar mixture over it. Give it a shake and let it marinate for at least 40 minutes before using. The longer it sits the better!
Make your chickpeas: Preheat the oven to 400 F. Toss your chickpeas in the spices and olive oil, and layer on a parchment lined baking sheet. Bake for 25 minutes, giving the pan a shake in between. Turn the oven off, and let the chickpeas sit in the closed oven for an additional 5 minutes.
Prep your dressing: while the chickpeas bake, prep your tahini dressing by whisking together all of the ingredients in a bowl. Start with 4 tbsp of water, and add more as needed to thin out the dressing. Adjust salt as needed.
Mix in your kale: Pour the dressing over the kale, and massage it in to soften it. I like to mix my dressing into the kale while the chickpeas bake to let it soak up the flavors.
Prep your salad: Once your chickpeas are cooked, toss them over the salad with about 1/3-1/2 of the pickled onions.
The leftover onions should stay fresh in the fridge for up to 2 weeks. Leftover dressing can be stored in the fridge for up to 1 week.
