Ingredients

• 4 links (about 1 lb) Italian sausage links
• 1 large, sliced into 1-inch strips red bell pepper
• 1 large, sliced into 1-inch strips yellow bell pepper
• 2 medium, sliced into 1/2-inch rounds zucchini
• 1 medium, cut into wedges red onion
• 3 tbsp olive oil
• 1 tsp dried oregano
• 1/2 tsp dried thyme
• 1 tsp salt
• 1/2 tsp black pepper
• 1/4 cup, optional grated Parmesan cheese

Instructions

1. Step 1: Preheat oven to 425°F. On a large rimmed baking sheet, arrange 4 Italian sausage links and surround them evenly with 1 large sliced red bell pepper, 1 large sliced yellow bell pepper, 2 medium sliced zucchini rounds, and 1 medium red onion cut into wedges.
2. Step 2: Drizzle 3 tbsp olive oil over the sausage and vegetables. Sprinkle 1 tsp dried oregano, 1/2 tsp dried thyme, 1 tsp salt, and 1/2 tsp black pepper evenly over everything. Toss vegetables gently with your hands to coat well but keep sausage in place.
3. Step 3: Roast in the preheated oven for 25-30 minutes, turning sausages once halfway through, until sausages are cooked through and vegetables are tender and slightly caramelized.
4. Step 4: Remove from oven and sprinkle 1/4 cup grated Parmesan cheese over the vegetables if desired. Let rest for 5 minutes before serving.
