Lay the chickpeas on paper towels and get as much moisture off them as possible. If you have time allow them to sit and dry for a few hours. The drier they are, the crispier your chickpeas will be.
Preheat the oven to 425 degrees.
Toss the dried chickpeas in the spices, olive oil, salt and lime.
Roast for 25 minutes. Shake the pan and roast for 20 minutes more or until the chickpeas are crispy. Watch carefully near the end because there is a fine line between crispy and burnt!
Allow to cool and store in an airtight container.
Notes
** If your lime doesn't have a lot of juice, you might want to use the whole one!
