Teriyaki Shiitake Sushi Burgers

I decided to make these delicious sushi burgers I made them quite small so they were almost like sliders. The difference between these and my rice burgers is that you use seasoned sushi rice and do not cook the rice on top in a pan.
First make your sushi rice and season the rice ( I like to use the Clearspring brand sushi seasoning it makes things really easy.)
Then decide how big you want to make them and choose a small bowl and place clingfilm wrap inside. Then put some rice into the bowl and press down making burger buns.
Then make your teriyaki shiitake. Slice up some shiitake mushrooms and sauté in a little toasted sesame oil. Make your teriyaki sauce I used tamari,mirin and maple syrup. Add this to your mushrooms and reduce down.
After you have made all your tops and bottoms you can fill your sushi burgers. I first spread some vegan kewpie mayo on the bottom of the rice then added sliced cucumber then lettuce,red pickled cabbage,sliced avocado and a square of toasted nori, then I added the teriyaki shiitake mushrooms. Topping it with another burger rice bun a sprinkle of black sesame seeds and some dried kombu. I served these with soy sauce,pickled ginger and wasabi.
Perfect for a Hanami picnic or for entertaining guests.
