Cheese Pizza or Grilled Cheese?
The better choice: Grilled cheese.
Cheese is a good source of calcium and protein, no matter the dish, but this battle comes down to how and where the meals are made. Pizza probably comes from a delivery person; grilled cheese is usually made at home, where you can control the type of cheese, the amount of butter, and the bread. (Ward suggests reduced-fat Cheddar, Olivio spread in place of butter, and whole-wheat bread.) Plus, grilled cheese has built-in portion control. A large pizza often lingers for breakfast.
Keep in mind: A pizza is a better vehicle for vegetables, like red peppers, broccoli, and extra tomatoes, if you can slip them in.
