Open the chickpeas, drain and rinse them - pick out any skins
Dry the chickpeas well using a kitchen towel or paper towel and place them on a parchment lined baking sheet
Drizzle with olive oil and using your hands move the chickpeas around to ensure they are coated
Sprinkle salt and taco seasoning on the chickpeas and shake the pan gently to coat
Place the pan in a pre-heated oven for 10 minutes and check, gently touch and if they are still a little soft place them back in the oven for another 3 minutes
When they are golden brown and firm to the touch, pull them out and leave them on the pan for 5 minutes to finish crisping
Serve immediately
Notes
You can use any seasoning you like, or just salt and pepper. A neutral oil like grapeseed oil can be used in place of the olive oil.
