Cook the rice with 280 ml (1 cup plus 2 tbsp) of water: bring to a boil over high heat, cover, reduce to low and simmer for 15 minutes, then rest covered for 5 minutes. Stir in the rice vinegar while it is warm.
Preheat the oven to 200°C (400°F) with a rack in the centre and line a small baking tray with parchment.
Pat the salmon dry, place it on the tray and brush it with half the tamari.
Roast for 10 to 12 minutes, until the salmon flakes easily with a fork and reaches 63°C (145°F) in the thickest part.
Meanwhile, mix the Greek yogurt with the sriracha to make the spicy mayo. Dice the cucumber, grate the carrot and slice the avocado.
Fill the bowls with rice, then arrange the salmon in chunks with the edamame, cucumber, carrot and avocado.
Drizzle with the remaining tamari and the spicy yogurt and finish with sesame seeds and sliced green onion.
Tips
Leftover salmon is perfect here; the bowl is meant to be eaten warm or cold.
Swaps
Soy-free: use coconut aminos and leave out the edamame.
