1. Pick the right cheese:
When it comes to grilled cheese, not all cheese is created equal. Some people love American cheese. It has superior melting qualities, but it falls short on flavor (not to mention that it’s not even really cheese to begin with). So skip mild-flavored cheeses and opt for ones with a stronger flavor—like sharp, or even extra-sharp, Cheddar. You’ll get more bang for your buck and because it’s big on flavor you won’t have to use as much, which helps cut fat and calories.
