Preheat Oven: Set the oven to 400°F (200°C) and line a large rimmed baking sheet with foil.
Prepare the Salmon:
Place 4 salmon fillets on one side of the prepared baking sheet.
Sprinkle evenly with ¼ teaspoon salt and ⅛ teaspoon pepper.
In a small bowl, whisk together 1½ tablespoons mayonnaise, 1 tablespoon gochujang, and 1 teaspoon honey. Brush this mixture evenly over the tops and sides of each fillet.
Prepare the Broccoli:
Toss 3 cups broccoli florets, 1 tablespoon olive oil, and the remaining ¼ teaspoon salt and pepper together.
Spread it on the other side of the baking sheet.
Roast:
Roast in the oven until the salmon is cooked through and an instantread thermometer inserted into the thickest part of the salmon reads 145°F, about 14 to 16 minutes.
Assemble the Bowls:
Place ½ cup of cooked rice in each of 4 shallow bowls.
Layer each bowl with 1 salmon fillet, about ⅓ cup of roasted broccoli, and ¼ cup of kimchi.
Top with ¼ cup sliced scallions and 1 tablespoon toasted sesame seeds.
Serve:
Serve with lime wedges, if desired, for an extra burst of freshness!
