Preheat oven to 350 degrees F.

On a clean dish towel or between several paper towels, dry rinsed chickpeas completely.

Place in a bowl with taco seasoning and olive oil. Toss to coat.

On a baking sheet sprayed with non-stick spray, spread chickpeas in one even layer. Bake in preheated oven for 55-60 minutes, taking out halfway through and shaking the sheet so the beans cook evenly. At the end of the baking time, the beans should be dried, dark brown (but not burnt), and crispy.

Remove from oven and let cool completely. Once cooled, they are best eaten within a day in order for them to stay crispy.
