We tried the healthiest thing you can order at In-N-Out burger - and it's not bad!

In-N-Out may be famous for its loaded hamburgers...

But the "secret menu" offers one healthier option...

BEHOLD: The "Protein Style" burger!

Forget the bun, this beef patty is wrapped with hand-leafed lettuce.

The ingredients are simple: lettuce...

Tomatoes...

A beef patty...

And voilà!

Okay, fine, it looks really plain and boring next to a fully loaded burger, but you're free to dress it up with ketchup and mustard.

But the meat was flavorful enough to stand on its own.

The whole thing is only 240 calories — and comes with a free hat!

Wouldn't you rather save your calories for In-N-Out's "animal style" fries??
