Season the salmon fillet evenly with sea salt and black pepper.
Heat the avocado oil in a medium non-stick skillet over medium-high heat.
Place the salmon in the skillet and sear for 4 to 5 minutes per side until the skin is crispy and the flesh is cooked through.
In a small bowl, gently fold the rice vinegar into the warm cooked sushi rice until well combined.
Thinly slice the cucumber into rounds and the avocado into small wedges.
Using kitchen shears, cut the nori sheet into very thin strips.
Place the seasoned sushi rice in the base of a serving bowl.
Top the rice with the seared salmon fillet and arrange the cucumber, edamame, and avocado around it.
Drizzle the entire bowl with coconut aminos and garnish with the sesame seeds and nori strips.
