Spread the chickpeas directly onto a baking sheet and place in the preheated oven.
Roast for 25-40 minutes, removing once or twice throughout this time and stirring the chickpeas with a spoon to rotate them around the pan. Chickpeas are done when they are golden brown and crunchy. They will continue to harden a bit as they cool, but if they are at all soft in the middle return them to the oven for a few more minutes.
Once cooked, remove the baking sheet from the oven and let cool for 5 minutes.
Place the roasted chickpeas into a clean bowl. Toss with salt and pepper until evenly coated, adjusting to taste. (Different chickpeas will have stronger or more mild flavors and different amounts of sodium, pepper may be stronger or more mild, etc. Always go by your own taste buds.)
1/4 tsp fresh black pepper, 1/8 +1/4 tsp sea salt
Store in a bowl on the counter with a clean kitchen towel spread over it.
