Sure pizza is delicious (no one’s arguing that!), but it packs a ton of calories and is far from a health food. Fortunately, there is an easy way to fix the problem—spice up your slice by topping it with kale. Simply sauté kale with onions, and place on top of your cheesy pie before it bakes. You’ll get a big blast of vitamins and minerals with every amazing bite. To up the health factor, consider using part-skim mozzarella cheese, a whole-grain crust and whatever veggies you have on hand.
