Need a new snack to munch on at the office? Roasted chickpeas are a surprisingly delicious, protein-rich alternative to hitting the vending machine. To make them, simply preheat the oven to 400 degrees. Rinse, drain, and blot dry a 15.5-ounce can of chickpeas. Toss with a tablespoon of olive oil, sprinkle with salt, spread chickpeas on a baking sheet, and bake for 20 to 30 minutes, or until golden and crispy.
