Cook the rice. Be mindful that brown rice takes a bit longer to cook than white rice. In my rice cooker, it generally takes around 30 minutes to cook. This step can also be completed ahead of time.
Marinate the salmon. Cut the salmon into bite-size dice using a sharp knife. Place in a medium mixing basin. Combine soy sauce, rice vinegar, honey, and sesame oil in a mixing bowl. While you prepare the rest of the ingredients, marinade the salmon.
Make the spicy mayo. In a medium bowl, combine the mayo and sriracha. To mix, stir everything together.
Assemble the bowls. I told you it was fast! Fill a bowl halfway with cooked rice. Distribute the salmon over the rice. Surround it with cucumber, carrot, and edamame. On top, spread out the avocado. Sprinkle with sesame seeds. Drizzle with mayonnaise.
