Step 1   Prepare the sauce by adding the soy sauce, sweet sake and sugar into your saucepan, then boil it down until 1/3 of the amount is left. 

Step 2   Cut the green onions into smaller dices before mixing it together with the pickles, green onions, and cooked rice.

Step 3   Start each rice ball preparation by putting a rib slice onto a plastic wrap and seasoning it with salt. 

Step 4   Roll up a small portion of the cooked rice mix into a ball and place it on top of the rib slice.

Step 5   Making good use of the plastic wrap, roll up the meat around each rice ball carefully.

Step 6   Roast the meat roll in a covered pan for about 7 to 8 minutes.

Step 7   Drizzle the sauce prepared earlier on top of the rice balls to glaze them.

Step 8   Place them neatly on a plate or a bento and enjoy your meal!
