Preheat oven to 400 degrees Fahrenheit
Cut Salmon filet into bite size cubes
Make the salmon marinade by combining soy sauce, rice vinegar, sesame oil, gochujang, garlic, brown sugar, and ginger. Toss the cubes of salmon with the marinade until completely coated. Transfer to a lined baking dish.
Bake for 10 minutes at 400 degrees Fahrenheit, then broil at 500 degrees Fahrenheit for 2 minutes.
While the salmon bakes, assemble the toppings. Cut the cucumber and green onions into small rounds. Slice the avocado into cubes, and rough chop cilantro.
To serve, add rice to a serving bowl and add the salmon on top, garnish as desired.
