01 - In a bowl, combine soy sauce, maple syrup, rice vinegar, sesame oil, minced garlic, grated ginger, and chili flakes. Whisk thoroughly until blended.
02 - Place salmon fillets in a shallow dish or resealable plastic bag. Pour half of the marinade over the fillets, reserving the remaining marinade. Allow salmon to marinate at room temperature for 15 minutes.
03 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
04 - Arrange marinated salmon fillets on the prepared baking sheet. Brush with reserved marinade and bake for 12–15 minutes, or until salmon is opaque and easily flakes when tested with a fork.
05 - While salmon bakes, cook rice as directed and prepare vegetables: shred cabbage, julienne carrots, slice cucumber, and cut avocado.
06 - Divide cooked rice evenly among four serving bowls. Top each with red cabbage, carrots, cucumber, and avocado slices. Add a salmon fillet to each bowl.
07 - Drizzle each bowl with any pan juices from baking. Sprinkle toasted sesame seeds and green onions on top. Serve with lime wedges and additional soy sauce or sriracha as desired.
