Ingredients

• 1 lb Italian sausage links
• 1 large red bell pepper, sliced
• 1 large green bell pepper, sliced
• 1 large yellow bell pepper, sliced
• 1 medium yellow onion, sliced
• 3 cloves garlic cloves, minced
• 3 tbsp olive oil
• 1 tsp dried oregano
• 1 tsp dried basil
• 1/4 tsp red pepper flakes
• 1 tsp salt
• 1/2 tsp black pepper

Instructions

1. Step 1: Preheat oven to 400°F (200°C). Line a large baking sheet with foil or parchment paper for easy cleanup.
2. Step 2: Place 1 lb Italian sausage links on the baking sheet. Arrange 1 large sliced red bell pepper, 1 large sliced green bell pepper, 1 large sliced yellow bell pepper, and 1 medium sliced yellow onion evenly around the sausages.
3. Step 3: In a small bowl, combine 3 tablespoons olive oil, 3 minced garlic cloves, 1 teaspoon dried oregano, 1 teaspoon dried basil, 1/4 teaspoon red pepper flakes, 1 teaspoon salt, and 1/2 teaspoon black pepper. Drizzle this mixture evenly over the sausages and vegetables.
4. Step 4: Toss the vegetables gently to coat them in the oil and spices without moving the sausages. Roast in the preheated oven for 30-35 minutes, turning the sausages halfway through, until sausages are cooked through and vegetables are tender with edges slightly caramelized.
5. Step 5: Remove from oven and let rest for 5 minutes before serving.
