making your own delish high fiber & high protein snack. YUMMY! - Drain and rinse 1 can of chickpeas and add to a bowl. Add 1 tablespoon of olive oil, ½ teaspoon of salt, and ½ teaspoon of cayenne pepper and toss to coat. Arrange in a single layer on a foil-lined baking sheet and bake for about 15 minutes at 450 degrees.
