Wafu Burger

My husband and I love a Wafu Burger served at a small neighborhood restaurant.  It has an amazing topping of grated daikon with a gingery, soy flavor and was served on a bed of sauteed onions and bean sprouts.  At home I tried to recreate it with organic ground beef, lots of minced ginger, and a little soy sauce  and sesame oil.  Lightly mix until just combined, form into patties, and cook according to personal preference.  Unfortunately I realized a little too late that we were out of daikon.  I decided to top with beni shoga, a Japanese pickled ginger that I always have on hand for yakisoba.  It turned out pretty well, but I need to try again next time I have daikon on hand!
