Cut the salmon into approximately 1-inch cubes. Remove the skin if desired.
In a large bowl, whisk together the soy sauce or tamari, honey, sriracha, minced garlic, and water.
Add the salmon cubes and gently toss to coat. Marinate for 20 minutes or up to 1 hour in the refrigerator.
Heat a large skillet over medium-high heat and add a small splash of oil.
Remove the salmon from the marinade, allowing excess marinade to remain in the bowl. Add the salmon to the hot skillet.
Cook for 2–3 minutes per side, turning carefully, until the salmon is nicely browned and cooked through.
Pour the reserved marinade into the skillet and cook until it bubbles and thickens into a glossy sauce. For food safety, make sure the marinade reaches a full simmer since it has been in contact with raw salmon.
To assemble the Honey Sriracha Salmon Bowls, divide the cooked rice between serving bowls.
Add the salmon, avocado, cucumber, and edamame.
Drizzle with sriracha mayo and finish with sesame seeds and red pepper flakes, if desired. Serve immediately.
