Pat the sushi-grade salmon dry with a paper towel and cut into uniform 1/2-inch cubes.
In a small glass bowl, whisk together the coconut aminos, toasted sesame oil, rice vinegar, lime juice, sea salt, and black pepper to create the marinade.
Add the salmon cubes to the marinade, tossing gently to ensure every piece is well-coated, then set aside in the refrigerator for 10 minutes.
While the salmon marinates, place the cauliflower rice in a skillet over medium heat and sauté for 3-5 minutes until tender and moisture has evaporated.
Thinly slice the cucumber into half-moons and finely chop the green onions.
Assemble the bowl by placing the warm cauliflower rice at the base, then topping with the marinated salmon, edamame, and sliced cucumbers.
Garnish the bowl with fresh green onions and a sprinkle of sesame seeds before serving immediately.
