Actor and producer Adrian Grenier is collaborating with cheese brand Jarlsberg to celebrate one of the world's most beloved comfort foods: the grilled cheese.

In a new global campaign, the actor – now also a farmer – shares how he prepares his favorite cheesy classic and calls on fans to share their creations.

"Something as simple as grilled cheese becomes next level with the right cheese, and the meltability and nutty taste of Jarlsberg are still unmatched in my book," says Adrian Grenier. "I strongly believe in natural, high-quality ingredients, and as I learned more about the brand, I was also struck by their commitment to quality."

Celebrating 70 years of meltability this year, Jarlsberg has become a familiar part of grilled cheese traditions for generations around the world. Its signature flavor and distinct holes are credited to its unique Norwegian recipe, which is carefully guarded and known by only a few.

"This collaboration is a celebration of Jarlsberg and the endless creativity of grilled cheese lovers," said Shibani Potnis, chief marketing officer for Norseland, Inc., parent company of Jarlsberg US. 

To bring consumers into the experience, Adrian also introduces the #JarlsbergMelt challenge, launching May 4, inviting fans to share their creative take on this classic for a chance to win one of Jarlsberg's world-famous 22-pound wheels – enough to make more than 100 grilled cheese sandwiches.
