Pat the salmon fillet dry with paper towels and season both sides with sea salt and black pepper.
In a small glass bowl, whisk together the coconut aminos, rice vinegar, grated fresh ginger, and minced garlic to create the glaze.
Heat half of the toasted sesame oil in a non-stick skillet over medium-high heat.
Place the salmon in the skillet skin-side up and sear for 4 minutes until a golden crust forms, then flip and cook for another 3-4 minutes.
During the last minute of cooking, pour half of the ginger glaze over the salmon to caramelize slightly, then remove the fish from the pan.
Add the remaining sesame oil to the same skillet and sauté the cauliflower rice and edamame for 3-5 minutes until tender-crisp.
Stir the remaining glaze into the cauliflower rice and transfer to a serving bowl.
Top the rice with the seared salmon, sliced cucumber, and thinly sliced radishes.
Garnish with sesame seeds and serve immediately while warm.
