Preheat oven to 400°F. Spray a 2-quart or 11-by-7-inch baking pan with avocado oil spray.
In a small bowl, combine vinegar, sugar, and salt, and stir until dissolved. Add warm rice to a large bowl, then fold in vinegar mixture.
Spread seasoned rice into bottom of prepared baking dish, packing it down firmly. Top evenly with a generous sprinkle of furikake.
In a medium bowl, add Surimi and shred using two forks. Then add cream cheese, Dynamite Sauce, soy sauce, and two thirds of the green onions and mix with a spatula to combine. Evenly spread surimi mixture over the furikake layer, gently packing it down.
Bake for 20-25 minutes, until rice begins to brown at edges and the surimi mixture is heated through. Let cool for 5-10 minutes. Drizzle with more Dynamite Sauce, a sprinkle of furikake, and the remaining green onions.
To serve, scoop spoonfuls of the sushi bake atop sheets of roasted seaweed and serve with avocado and cucumbers.
