In a bowl, whisk together soy sauce, honey, sriracha, garlic, and water to create the marinade.
Add salmon cubes to the marinade and let sit for at least 20 minutes.
Heat sesame oil in a skillet over medium heat. Add salmon cubes (reserve extra marinade) and cook for 2-3 minutes per side until crispy.
In a small pan, simmer the reserved marinade until thickened into a glaze.
Assemble bowls by layering rice, cucumber, edamame, and avocado.
Top with crispy salmon, drizzle with thickened sauce and sriracha mayo.
Garnish with sesame seeds and red pepper flakes. Serve immediately!
