Roasted chickpeas are a delicious, low-carb, good-for-you snack. (Emphasis on the delicious, who cares about the other parts if it doesn't taste good?)
Preheat oven to 400 degrees. Take one can of chickpeas and drain them (really well, excess liquid means they won't get as crispy as they could). Spread them on a baking sheet lined with foil. Pour some olive oil on them and kind of roll the chickpeas around in it so they're pretty well coated with the oil. Season them however you like--we just do salt and black pepper but you could make these spicy or basically do whatever you like.
Bake for 20-25 minutes. Keep an eye on them because depending on the brand of chickpeas, you may need to bake them longer for them to be really crispy and crunchy. When you take them out of the oven, just scoop them onto a plate and eat them!
