1. Rinse the rice until the water runs clear. Transfer it to a rice cooker or pot and add in the appropriate amount of water depending on your packaging directions (we used 3 cups). Soak the rinsed rice in the water for 30 minutes before cooking. If you are using a rice cooker, set it to cook (set it to “sweet rice” if you have the option). If you are cooking it on the stovetop, bring the soaked rice to a boil. Once boiling, cover the pot with a lid and reduce heat to low simmer. Cook for 20 minutes and then remove the pot from heat (do not remove the lid) for 10 minutes. Once set, uncover and fluff with a fork.
2. Once cooled, mix in the seasoned rice vinegar, adding more as desired to taste.
3. Press the rice into the bottom of the baking dish and then sprinkle it with 2 tablespoons of furikake.
4. Evenly layer on the julienned carrots followed by the sliced cucumbers. Lastly, add the avocado on top as desired. What we like to do is score the avocado into thin squares, scoop the whole avocado out onto the casserole and spread it over with a spatula to get a flat and smooth layer. Sprinkle the remaining 2 tablespoons of furikake on top + more as desired.
5. Slice the sushi casserole as you would a lasagna and serve with a side of nori. We like to eat this casserole with our hands, as you would sushi! Grab the nori sheet, and using either your hands or a spoon, scoop off a piece of the casserole into the nori sheet and dig in!

Homemade Furikake

1. Put all ingredients except the sesame seeds in a blender/food processor and pulse until a coarse meal is formed (you still want each ingredient to be visible).
2. Pour the blended contents into a large bowl and mix in the sesame seeds. Transfer it to an airtight container and store it in a cool and dry place.
