Preheat oven to 400°F(200°C). Lightly grease a baking sheet.
Allow the chickpeas to air dry before beginning, or pat dry with a paper towel.
In a small bowl, combine cumin, paprika, garlic powder, onion powder, coriander, salt and pepper. Set aside.
Spread chickpeas out on the baking sheet.
Bake for 15 minutes.
Remove the chickpeas from the oven and drizzle with olive oil, stirring to coat. Sprinkle on the spices and stir to coat.
Bake for 10 more minutes. Stir the chickpeas around on the baking sheet, and continue cooking for
5-10 minutes, until desired crispiness is achieved.
Turn off the oven and open the oven door so it's slightly ajar. Let the chickpeas cool in the oven.
