Measure the rice and wash it until water is clear. Place rice and water in pot on high heat and bring to a boil with lid on. Once you bring it to a boil, switch to low heat. Cooking times will vary.
While the rice is cooking, set your oven to 400 degrees Fahrenheit.
Wash the veggies and cut the eggplant into diagonal squares and the sweet potato into a fry shape. I included the pictures below how to cut the veggies.
Use a reusable clean towel to let the veggies lay and dry for 2 mins. Add salt to draw out the moisture from the veggies. Before transferring the veggies to the baking pan add the oil. Once the oven is ready add them to the oven.
In a small pot, on low to medium heat, add the unagi sauce ingredients but wait to poor the slurry last. Mix until it thickens. Transfer to a little sauce bowl after it gets thick and boils.
Once the veggies have been in there for about 10-12 minutes, add the unagi sauce and bake for another 3 mins. Keep an eye on it if the sauce on the fruit and veggies burns.
In the meantime, cut a nori sheet into 4 inch long stripes.
Use a tablespoon to scoop up the rice into your hand. You can wet your hands with water, so the rice doesn't stick to your hands. Get two tablespoons of rice and form them into an oval shape in your hand.
Add the eggplant on top of the rice ball. Wrap the seaweed piece around the ball like how I did in the image below, and you may use water to stick the seaweed together. Now it is ready to serve! Feel free to top it off with roasted sesame seeds. Don't forget to enjoy the sweet potato if you end up cooking it!
