Preheat oven to 400°. Lay a piece of tin foil on a baking pan and set aside.
Drain, rinse, and pay dry the can of chickpeas. Use a paper towel or dish towel to wipe off the outer later of the chickpeas to make them even crispier.
Place the chickpeas in a small mixing bowl and add the olive oil, salt, and pepper. Toss to combine.
Lay the chickpeas in a singler layer on the prepared baking pan.
Bake for 30 min. Take out baking pan and give it a shake every 10 minutes to ensure the chickpeas toast on all sides.
Add cumin, chili powder, and garlic powder and bake for another 8 minutes.
