Instructions

1. Step 1: Preheat oven to 425°F. Line a large baking sheet with parchment paper. Place 4 Italian sausage links (about 1 lb) on the sheet.
2. Step 2: In a large bowl, combine 1 sliced red bell pepper, 1 sliced yellow bell pepper, 1 sliced green bell pepper, and 1 sliced large yellow onion. Add 3 minced garlic cloves, 3 tbsp olive oil, 1 tsp dried oregano, 1/2 tsp dried thyme, 1 tsp salt, 1/2 tsp black pepper, and 1/4 tsp red pepper flakes if using. Toss well to coat all vegetables.
3. Step 3: Spread the vegetable mixture evenly around the sausage links on the baking sheet. Roast in the preheated oven for 25-30 minutes, turning sausages halfway through, until sausages are browned and cooked through and vegetables are tender with slightly charred edges.
4. Step 4: Remove from oven and let rest for 5 minutes before serving to allow flavors to meld.
