Season the salmon fillet evenly with sea salt, black pepper, and garlic powder.
Heat a non-stick skillet over medium-high heat with 0.5 tsp of the toasted sesame oil.
Place salmon in the skillet skin-side up and sear for 4 minutes, then flip and cook for 3-4 minutes until crispy and cooked through.
Remove the salmon from the pan to rest, then add the remaining 0.5 tsp sesame oil and cauliflower rice to the same skillet.
Sauté the cauliflower rice with fresh ginger and tamari for 5 minutes until tender and aromatic.
Steam or microwave the shelled edamame until heated through and slice the cucumber into thin rounds.
Assemble the bowl by layering the cauliflower rice at the base, topped with the flaked salmon, edamame, cucumber, sesame seeds, and green onions.
