First, make sure the rice is cooked and ready to go.

Prep the ingredients. The crab and cilantro should be finely chopped. The cucumber and avocado can be cut into larger chunks.

Make the spicy mayo. In a small bowl, add the mayo and Sriracha. Set aside or cover and refrigerate until ready for use.

Add the soy sauce, sugar and mirin to a small saucepan or skillet. Cook over medium heat until it boils, stirring occasionally.

Once boiling, reduce heat to low and let it simmer for about 5 minutes, stirring occasionally. Remove the pan from heat and let it cool off.

Add one cup of Panko breadcrumbs to a small skillet. Drizzle ¼ cup of olive oil on top of the Panko.

Turn heat to medium and mix the Panko and olive oil well, until all the Panko is coated.

Let it cook for about 2-3 minutes and stir it when you see it start to turn gold brown around the edges.

Stir frequently for about another minute or two, until most of the Panko is a golden brown.

Remove pan from heat and transfer Panko to a plate until ready for use.

Scoop rice into a bowl.

Top with crab, cucumber, avocado and cilantro.

Drizzle desired amount of eel sauce, followed with a drizzle of spicy mayo.

Sprinkle toasted Panko crumbs on top.

Enjoy!
