Add the cubed salmon to a medium bowl and add the marinade ingredients. Toss until well coated, then cover the bowl and let it marinate in the fridge for 30 minutes.
While the salmon marinates, bring the rinsed rice and water or broth to a boil, cover, reduce the heat to medium-low and cook for however long the package suggests (this will vary depending on the type of rice you use).
Heat a large skillet over medium heat with 1 tablespoon of oil. Once hot, add in the marinated salmon cubes and arrange them in a single layer. Cook on one side for 4 minutes, flip over and cook another 2-3 minutes, depending on your preference of doneness.
Arrange in bowls by adding the rice, salmon, vegetables, avocado, and a drizzle of sauce.
