Pat the salmon fillet completely dry with paper towels and season both sides with sea salt and black pepper.
Heat avocado oil in a non-stick skillet over medium-high heat until shimmering.
Place salmon skin-side down in the pan and press firmly with a spatula for 30 seconds to ensure even contact.
Sear for 4-5 minutes until the skin is golden and crispy, then flip and cook for another 2 minutes for medium doneness.
In a small bowl, whisk together the Greek yogurt and sriracha to create a creamy, spicy drizzle.
Toss the cooked sushi rice with rice vinegar and coconut aminos, then place in the center of a serving bowl.
Arrange the crispy salmon, sliced cucumber, radishes, and edamame over the rice.
Garnish with torn nori sheets and sesame seeds before drizzling with the spicy yogurt sauce.
