Boil the sweet potato cubes with salt until tender.
Meanwhile, prepare the salmon:
Line a baking sheet with parchment paper.
Mix soy sauce and honey.
Place salmon fillets on parchment, brush with the glaze.
Fold the parchment to create a sealed pouch.
Bake the salmon for about 12 minutes, or until cooked through (approximately 450ºF/230ºC).
Assemble the salad: Toss the spring mix with grape tomatoes and drizzle with balsamic vinegar.
Drizzle the sweet potatoes with olive oil and season with fresh ground pepper.
Plate the salmon, sweet potato, and salad. Garnish with chopped green onion and enjoy!
