In a small bowl, whisk together soy sauce, honey, garlic, ginger, and olive oil to make the glaze.
Place salmon fillets on a baking sheet lined with parchment paper. Season with salt and pepper.
Brush the glaze over the salmon fillets, ensuring they are well coated.
In a separate bowl, toss the sliced bell peppers, zucchini, and red onion with balsamic vinegar, olive oil, salt, and pepper.
Spread the vegetables on a separate baking sheet.
Place both the salmon and vegetables in the oven and roast for 15-20 minutes, or until the salmon is cooked through and the vegetables are tender, flipping the vegetables halfway through.
Once done, remove from the oven and let it rest for a few minutes.
Serve the honey soy glazed salmon on a bed of roasted vegetables, garnish with fresh parsley, and enjoy!
