Drain, rise and remove the skins from your chickpeas (see description above for my favorite way to do this). Set aside.
Heat olive oil in a pan over medium heat. Add red onion and sauté for 2 minutes. Add chickpeas and taco seasoning to the pan. Pour 1/4 cup of water in the pan and simmer for 5-7 minutes (or until most of the water is evaporated).
Using a potato masher (or a fork), mash chickpeas until your desired consistency is reached. Turn heat to low until ready to eat - adding additional water 1 tablespoon at a time if it starts to dry out.
Combine lettuce, cabbage and lime juice in a bowl. Stir to combine and set aside until ready to use.
In a pan (or over an open flame), grill tortillas until warmed through and slightly crispy.
To assemble tacos, layer each tortilla with 1/4 cup of chickpea mixture, slaw and any toppings you are using. Drizzle Jalapeño Cream Sauce over each taco and serve.
