Lightly spray a baking sheet with non-stick spray. Set aside.
Rinse and thoroughly dry the chickpeas.
In a small bowl, mix together cumin, paprika, garlic powder, sea salt, onion powder and pepper. Set aside.
Bake dried chickpeas in the preheated oven on prepared baking sheet for 15 minutes (do not add any of the other ingredients yet)!
Remove the chickpeas from the oven and drizzle ½ TBS olive oil over the chickpeas, stirring until evenly coated. If necessary, slowly add more olive oil until all the chickpeas are lightly coated with olive oil.
Add spices to chickpeas and stir until evenly coated.
Bake at 400 for 10 more minutes, then stir.
Return stirred chickpeas to the oven and bake them for an additional 5-10 minutes, until desired crispiness is achieved (a total of 35-40 minutes of baking).
Turn off oven and crack the door a bit. Let chickpeas cool in the oven to achieve maximum crispiness
