In a medium skillet heat chickpeas with lime juice and chili powder over medium-high heat until the chickpeas are heated through and are lightly brown.
Heat tacos over a flame on the stove until lightly charred, (I have a gas stove if you have electric use a pan)
Portion out chickpeas onto tacos, add cabbage, green onion, cotija cheese, add some avocado and squeeze some lime over top (salt and pepper to taste)
