Ingredients

• 1 lb spicy Italian sausages
• 2 medium, sliced into strips red bell peppers
• 2 medium, sliced into strips yellow bell peppers
• 1 large, sliced into wedges red onion
• 3 tbsp olive oil
• 1 tsp dried oregano
• 1/2 tsp crushed red pepper flakes
• 1 tsp kosher salt
• 1/2 tsp freshly ground black pepper

Instructions

1. Step 1: Preheat oven to 425°F and line a large sheet pan with parchment paper. Arrange 1 lb spicy Italian sausages on the pan along with 2 sliced red bell peppers, 2 sliced yellow bell peppers, and 1 large sliced red onion.
2. Step 2: Drizzle 3 tbsp olive oil over the sausages and vegetables. Sprinkle 1 tsp dried oregano, 1/2 tsp crushed red pepper flakes, 1 tsp kosher salt, and 1/2 tsp freshly ground black pepper. Toss the vegetables gently to coat them evenly, leaving the sausages in place.
3. Step 3: Roast in the oven for 25-30 minutes, turning the sausages halfway through, until the sausages are cooked through and the peppers and onions are tender and caramelized at the edges.
