In a 8x8 baking dish, whisk together the Miso Maple Marinade. Add miso paste, maple syrup, sesame oil, rice vinegar, soy sauce, ginger and garlic cube. Whisk until smooth.
Remove salmon from it's packaging and gently pat dry with paper towels. Place salmon in the dish with the miso maple glaze, cover with plastic wrap, and let sit for at least 30 minutes up to overnight.
Preheat the oven to 425°F degrees and grab a baking sheet and line it with parchment paper (aluminum foil on the sheet pan is also fine if you don't have parchment, but make sure you spray with cooking spray so the salmon doesn't stick).
Place the salmon filets on the prepared sheet pan and bake for 8-10 minutes or until the internal temperature reaches 165°F. Middle racks in the middle of the oven is best for the most even cooking.
While the salmon is cooking, make the rice according to box instructions.
Heat a skillet to medium heat with sesame oil. Cut the mini bok choy bundles in half, longways. Add the soy sauce, rice vinegar, salt, and red pepper flakes to the hot skillet. It will sizzle, then add the bok choy faced down. Cover and allow to sauté for 5 minutes. Bok Choy should be wilted but still firm.
Build the bowl: layer rice, bok choy and cooked salmon together on a plate or bowl. Top with sesame seeds, chopped green onions and balsamic glaze drizzle (optional)!
