Cook the brown rice according to package directions or use pre-cooked rice warmed through.
In a small glass jar, whisk together the tamari, rice vinegar, grated fresh ginger, and sesame oil to create the dressing.
Pat the shrimp dry with a paper towel and season with sea salt and black pepper.
Heat a large non-stick skillet over medium-high heat and add the shrimp, cooking for 2-3 minutes per side until pink and opaque.
Steam the shelled edamame for 3 minutes until tender and bright green.
Thinly slice the cucumber into rounds and the avocado into wedges.
Place the cooked brown rice in the center of a wide bowl.
Arrange the sautéed shrimp, edamame, cucumber, and avocado in sections around the rice.
Drizzle the ginger-tamari dressing evenly over the entire bowl.
Garnish with sliced green onions and torn pieces of nori seaweed for a salty crunch.
