Dry off the chickpeas with a paper towel
In a bowl, toss the chickpeas with olive oil, corn flour and season to taste with salt, paprika powder, and black pepper.
Spread on a baking sheet.
Bake for 20 to 30 minutes, until browned and crunchy. Be careful with the last few minutes to avoid any burning.
They can be kept in a sealed jar in the refrigerator for about 3 to 4 days
