In a small bowl, whisk together the coconut aminos, rice vinegar, and garlic powder to create the dressing.
Pat the raw shrimp dry with a paper towel and season evenly with sea salt.
Heat the toasted sesame oil in a large skillet over medium-high heat until shimmering.
Add the shrimp to the skillet and sear for 2 to 3 minutes per side until pink, opaque, and slightly caramelized.
Place the warm cooked brown rice in the center of a serving bowl.
Arrange the seared shrimp, shelled edamame, sliced cucumber, and avocado slices around the rice.
Drizzle the prepared dressing over the entire bowl to coat the ingredients.
Garnish with torn nori seaweed sheets, sliced green onions, and sesame seeds before serving.
