Ingredients

• 4, about 1 lb Italian sausage links
• 1 large, sliced into 1/2-inch strips red bell pepper
• 1 large, sliced into 1/2-inch strips yellow bell pepper
• 1 large, sliced into 1/2-inch strips green bell pepper
• 1 large, sliced into 1/2-inch wedges yellow onion
• 4, thinly sliced garlic cloves
• 3 tbsp olive oil
• 1 tsp dried oregano
• 1/2 tsp dried thyme
• 1 tsp salt
• 1/2 tsp black pepper
• 1/4 tsp optional red pepper flakes

Instructions

1. Step 1: Preheat oven to 425°F. On a large rimmed baking sheet, toss 1 sliced large red bell pepper, 1 large yellow bell pepper, 1 large green bell pepper sliced into 1/2-inch strips, 1 large yellow onion sliced into 1/2-inch wedges, and 4 thinly sliced garlic cloves with 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.
2. Step 2: Arrange 4 Italian sausage links evenly on top of the vegetables. Roast in the oven for 25-30 minutes, turning the sausages halfway through, until the sausages are cooked through and browned and the vegetables are tender and caramelized at the edges.
3. Step 3: Remove from oven and let rest for 5 minutes before serving. Slice sausages if desired and serve with the roasted peppers and onions.
