Preheat oven to 350°F. Meanwhile, spread chickpeas out on a few layers of paper towels or a clean kitchen towel and gently pat dry.
In a large bowl, add dried chickpeas, oil, and salt, and toss to coat.
Spread chickpeas out on a large, rimmed baking sheet, making sure they’re in one even layer. Bake for 20-30 minutes, shaking the pan every 10 minutes, until they’re crispy.
Sprinkle the warm chickpeas with the Garam Masala and toss to coat. Serve warm.
