Indian Kale with Chickpeas

Heat oil in a large frying pan or wok over medium-high heat. Add onion and chile pepper; saute until onion is tender, 5 to 7 minutes. Add chickpeas, cumin, coriander, turmeric, cinnamon, and salt; saute for 5 minutes. Pour in a splash of water, followed by lemon zest and juice. Season further to taste if desired.

Fold kale into the mixture until just wilted, 3 to 5 minutes. Remove from heat and serve.
