Preheat the oven to 375 degrees.

In a large mixing bowl, mix together oil, salt and spices.

Add chickpeas and toss well to coat.

Spread seasoned chickpeas on a baking sheet in a single layer.

Cook 30-35 minutes, stirring occasionally. Toss well after 35 minutes, and taste to see if they are finished. Chickpeas are done when they are crunchy but not burned. They may need up to an additional 15-20 minutes to get crunchy enough, but check them frequently and stir them often, as they go from finished to burned very quickly.

Note: If they aren't cooked enough, they will have a semi-firm texture.
