Step 1

In a 1-gallon zip-top plastic bag, combine the soy sauce, honey, vinegar, Sriracha, ginger, and garlic. Add the salmon, toss to coat evenly, and refrigerate for at least 1 hour, or up to 8 hours, turning the fish once.

Step 2

Remove the salmon from the bag, reserving the marinade. Heat a large sauté pan over medium-high heat and add the sesame oil. Rotate the pan to coat the bottom evenly and add the salmon. Cook until one side of the fish is browned, about 2 minutes. Flip the salmon and cook until the other side browns, 2 more minutes. Reduce the heat to low and pour in the reserved marinade. Cover and cook until the fish is cooked through, 4 to 5 minutes.

Step 3

Place a piece of salmon on each of 4 serving plates and sprinkle with the scallions.
