Cheese. Do you need it?
If you answered "yes", then here's what to do:
One slice of cheese is usually around 110 calories, but with shredded cheese, you have greater control over portion size, and can easily cut back on the amount used while still covering the same amount of area. You'll probably notice, too, that the less cheese you eat, the more you realize the food that would have been underneath have fantastic flavors of their own. I've even gotten to the point where I often realize that I didn't even need to have the cheese in the first place, and go without it the next time, freeing up calories for more of something else! As with anything (erm, most things), you don't have to give it up entirely, just dial it back a notch or two.
