Preheat oven to 450°F degrees.

Blot chickpeas with a paper towel to dry them.

In a bowl, toss chickpeas with olive oil, and season to taste with salt, garlic powder, paprika, ginger, turmeric, and cayenne pepper, if using.

Spread on a baking sheet, and bake for 30-40 minutes, until browned and crunchy. Watch carefully the last few minutes to avoid burning.
