Preheat oven to 400 F and spray large 9x13 baking dish with cooking spray. Set aside.
Cook 2 cups of rice on the stovetop or I like to make it in Instant Pot. Add rice, water and salt, then pressure cook on High pressure for 5 minutes and allow for complete or 10 minutes of Natural Release. You want rice soft and mushy so it sticks.
While rice is cooking, in a large bowl add salmon, Thai sweet chili sauce and salt. Stir and set aside to marinate.
While salmon is marinating, make spicy mayo sauce by whisking mayo, sriracha, soy sauce and maple syrup in a medium bowl. Set aside.
In previously prepared baking dish add rice and level it with a spoon, pressing on it so it's packed. Then top with roasted seaweed and marinated salmon in a single layer. Bake for 15 minutes, then broil until golden brown.
Remove sushi bake from the oven and drizzle with spicy mayo sauce. Then garnish with edamame, cucumber, green onion and sesame seeds. Drizzle with Japanese BBQ sauce.
Serve hot by cutting each slice with a spatula.

Notes
Store:Â Refrigerate in an airtight container for up to 5 days.
I don't recommend to freeze this dish because of all the toppings. Unless you plan ahead and top half of the bake only. Then freeze the other half tightly wrapped with a few pieces of plastic wrap for up to 3 months. Thaw in the fridge overnight and reheat in a microwave for a few minutes or in the oven at 350 F for 10-15 minutes.
