Wandering Adventure Party

Looks delicious! I like the pops of color the mayo and avocado lend to the dish. I started making a similar dish recently, except I marinated the salmon for ~3 hours in 1 part sake, 1 part soy sauce, and 3 parts mirin. Drizzling the remaining marinade from the pan over the salmon/rice makes it divine, but it does look a little plain by itself. Might follow your example and add some colorful sides!
