Instead of a hamburger try this. Serve with a nice stir fry of fresh veggies. To make it spicy just add some chili flakes or Szechuan Sauce.I also put a 1/2 tsp of Wasabi on the bun but only do that if you like it hot. I felt like something different than my regular Saturday Hamburger and this recipe was the result. If you do not wish to use sherry substitute with Sake or apple juice.
