Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.

Chop the bell peppers and asparagus; spread them on the baking sheet.

Drizzle olive oil over the veggies, season with salt and pepper, and toss to combine.

In a small bowl, whisk together soy sauce, honey, orange juice, minced garlic, and orange zest. Reserve half for later.

Place salmon fillets in the center of the vegetable mix; drizzle with remaining sauce and top each fillet with orange slices.

Bake for 15-20 minutes until salmon flakes easily with a fork.
