Preheat oven to 400°F. Spread chickpeas on a clean towel and rub them dry, discarding any loose skins. Place the chickpeas in a bowl and toss them with the avocado oil, turmeric, cumin, salt and pepper until well coated. Spread them on a baking sheet lined with parchment and roast, stirring half way through, for about 30 minutes, or until crisp. Set aside.
