Preheat the oven to 350.
Drain and rinse the chickpeas. Put the chickpeas on a baking sheet, and roast for 20 minutes. Shake them a little bit half way through.
Take them out and put into a bowl. Add the oil and the spices, as much as you want, and mix well. Turn the chickpeas back onto the baking sheet, and back in the oven for another 5-15 minutes. They're done when they're bronzed and VERY crunchy.
