Preheat your oven to 350 degrees f.
Place the peppers, onion, garlic, tomatoes, kale, and taco seasoning in a large bowl. Drizzle with your oil and thoroughly toss then rub with your hands to evenly season the veggies paying special attention to the kale.
Add in the chickpeas, chicken, and mayonnaise or Greek yogurt, sea salt and freshly ground black pepper to taste then toss well to combine.
Transfer half of your veggie-chicken mixture to a large baking dish and sprinkle with half of the cheese.
Repeat with the remaining half of the ingredients topping with cheese.
Cover your dish tightly with foil and bake in your preheated oven for 30 minutes, then uncover and broil for a few minutes, just until nicely golden-brown.
