Grilled Eel Japanese Style

I've been making this at home lately because it's so easy, all the ingredients are nonperishable and can be kept for whenever you are hungry with no food, and can be made for one person. I buy the eel at the Chinese supermarket. You can find it in the freezer aisle next to the frozen fish balls. It comes vacuumed sealed already seasoned with the sweet eel sauce. I usually cut myself half a piece and grill it in my toaster oven until the edges get nice and charred. I serve it on top of Korean or Japanese rice with seaweeed and sesame furikake seasoning and sliced avocados. It is delicious and so easy. Today I didn't have any avocados but I had some pickled spicy shiso that I made the other week. Deeeelicious!
