Cheese Burgerdon!

I was browsing through papadesuyo777's videos and I really wanted to try the Grilled Cheese Beef Bowl! I was missing some ingredients but it was still tasty! Instead of sliced beef I used hamburger! If you would like to try the original here is the video!:

Cheese Burgerdon! (serves 1 person)

1-2 patties of hamburger
1/4 or more onion, sliced thinly
1/4 cup cheese
a little parmesan cheese
1 green onion, chopped (garnish)
1-2 tablespoons water
less than 1/4 cup soy sauce
2 teaspoons vinegar
2 teaspoons mirin
1 tablespoon sugar
1 garlic clove, grated
1/2 to 1 teaspoon ginger, grated
About 2 tablespoons sesame seeds

1. Cook your burger patty(s) according to instructions. When it has cooled, chop to bite-size pieces.
2. Combine water, soy sauce, vinegar, mirin, sugar, garlic, ginger, sesame seeds and onion in a pan. Boil on medium heat.
3. When the sauce is boiling, add the burger and toss to coat it evenly. Turn off the heat. (You can actually stop here if you just want a hamburger rice bowl without cheese. Just place hamburger mixture on your rice and enjoy with green onion or pickled ginger!)
4. Place the hamburger mixture on a non-stick baking pan or a baking pan lined with foil. Pour excess liquid on your rice. 
5. Sprinkle on the cheeses and broil it in the oven on low for 5 minutes!
6. Serve the burger on your rice bowl and garnish with the green onion or pickled ginger! Enjoy!
