Preheat your oven to 400°F (200°C) and line a large sheet pan with parchment paper for easy cleanup.
Slice the chicken sausage into rounds and chop the red bell pepper into bite-sized pieces.
Place the broccoli florets, bell peppers, and sausage on the sheet pan, then drizzle with half of the olive oil and season with a pinch of salt and pepper.
Toss the vegetables and sausage to coat evenly and spread them out to the edges of the pan, leaving space in the center.
Place the salmon fillet in the center of the pan, drizzle with the remaining olive oil and lemon juice, and season with oregano, garlic powder, salt, and pepper.
Roast for 12-15 minutes until the salmon is flaky and the vegetables are tender with slightly charred edges.
Serve immediately, ensuring you get a mix of the savory sausage and the citrus-infused salmon in every bite.
