You can never go wrong with a grilled cheese sandwich. It's fast, cheap, and well, loaded with so much glorious melted cheese. Whether you like it with Cheddar, American or Swiss -- with or without tomatoes -- no one can deny the simple perfection of this sandwich.
We know that the very definition of perfection suggests that something does not need -- or even can't -- be improved upon, we've managed to find a way to make the grilled cheese sandwich EVEN BETTER than it already is. While some of you grilled-cheese purists might think this is impossible (or blasphemous even), just try these 15 instant upgrades and you'll see what we mean.
If you're feeling skeptical, just think about this: BLT grilled cheese.
