Heat a 12-inch skillet over medium-high heat. Drizzle in about 1 tablespoon of olive oil. When the oil is shimmery, transfer the salmon cubes to the skillet. Let the salmon get lightly opaque on one side before stirring and flipping the pieces of salmon. Basically we just want to sear the salmon on all sides. Don't let the salmon cook too long at this point.
When the exteriors are lightly opaque, add the teriyaki sauce and gently stir to coat the salmon in the sauce. Let the sauce caramelize and stir the salmon only occasionally.
When most of the sauce is caramelized and thickened, add the scallions to the pan and stir to combine.
When the last of the sauce is pretty much gone, cut the heat. We are ready to assemble our Teriyaki Salmon Rice Bowls. Add a serving of rice to a wide shallow bowl and sprinkle with sesame seeds. Spoon a serving of salmon onto the rice.
Spoon a serving of salmon onto the rice. Then place a small handful of the edamame and a few slices of avocado and pickled ginger. Top with a sprinkling of sesame seeds and togarashi. Serve hot, warm, or cold.
