Hamburger Steak Sushi

Makes about 8 sushi steaks

1. Finely chop about a quarter of an onion.

2. Fry chopped onions in frying pan until softened and set aside to cool. 

3. In a large bowl, soften the quarter cup of panko crumbs with three tablespoons of milk.

4. Add the meat and mix with your hands. Knead until the meat is sticky. You don't have to use 100% ground beef; you could use any combination of ground meat substitute, such as 50% ground beef - 50% ground pork or 100% ground turkey. Whatever is your preference. 

5. Add the sugar, soy sauce, ketchup, worcestershire sauce, and salt and pepper. Then knead it again until it is well mixed. 

6. Add the cooked onions you set aside and knead to mix.

7. Beat one egg in a bowl, then add to the meat mixture and knead. 

8. Once you have thoroughly mixed the meat, separate the meat into balls for the patties. Pass each ball back and forth between your hands to remove any air pockets. If the meat is too warm, you can place it back into the fridge to cool down a little. At this point, if you have too much meat, you can saran wrap a portion and freeze to make later. Make sure you've formed the meat into the patties you'll need next time before you store it.

9. Flatten each ball into patties. Indent the middles slightly so that they cook all the way through. Be sure to form the ground beef into cute, finger-shaped, sushi-sized patties!

10. Heat some cooking oil in a frying pan over medium heat, then place the patties in the pan. Flip over when each side is golden brown. This should take about a minute for each side.

11. Cover the frying pan and change the heat to low. Cook for about another minute. Uncover and check if each side is browned enough. Then remove from heat. Set aside. 

12. To make the sauce, use the same pan you just cooked the patties in. In a bowl, mix a 1:1 ratio of ketchup and worcestershire sauce together. We used about 1/4 cup of each, but you can change the amount depending on how many patties you are making. Mix in a little bit of water and stir until evenly combined. 

13. Add the sauce to the frying pan and cook the liquid down on low heat. Once it has been reduced a little, remove from heat and set aside. 

14. Top the rice with the patties. Drizzle the sauce on your two pieces.

15. Fight over a plate of two with your rival.

aw, they're so cute.
