Grilling doesn't have to be boring. Truffle burger with truffle mayonnaise and ketchup is easy to make and it's a great and hearty meal.
Grill the beef burger on the well heated grill pan.
Flip the burger when seared on one side and add a thin slice of truffle cheese near the end so it slowly melts.
Cut the buns in halves and toast them briefly.
Lay a grilled beef burger on top of it, add ketchup and truffle mayonnaise, finish with strips of lettuce.
Finally put a few slices of fresh black truffles.
