Pre-heat your oven to 425F
Combine all the marinade ingredients in a mixing bowl and whisk until brown sugar dissolves. Reserve 1 tbsp for brushing
Place salmon in a ziplock bag with the remaining marinade, seal and marinade at least 20 minutes
This is about the time you want to start the quinoa to package directions if you want it to be ready about the same time as the potatoes and the salmon
Toss the potatoes, onions, 3 tsp garlic with olive oil and a liberal amount of salt and pepper, move to a square baking pan and roast for 15 minutes
Once the salmon has marinaded for at least 20 minutes place the fillets skin side down on a parchment lined baking sheet.
Take the potatoes out after 15 minutes and turn them, return to the oven along with the salmon.
The salmon should cook in 12-15 minutes. Check it after 12 minutes and remove if the center of the largest fillet is 145F
When the salmon is cooked and the potatoes are fork tender, turn on the broiler. Brush the fillets with the marinade you set aside, then broil both for 2-3 minutes
Build the bowls, drizzle the potatoes with gochujang sauce or sriracha, garnish everything with sesame seeds and chopped green onion
