Instructions

• Preheat the oven to 400°F (200°C). Line a large baking sheet with parchment paper.
• In a large bowl, combine 12 ounces precooked sausage (cut into 1/2-inch rounds), 1 medium red bell pepper (sliced into 1/4-inch strips), 1 medium yellow bell pepper (sliced into 1/4-inch strips), and 1 small yellow onion (sliced into 1/4-inch strips).
• Drizzle with 1 to 2 tablespoons olive oil. Add 2 cloves minced garlic, 1 teaspoon Italian seasoning, kosher salt and black pepper to taste, and a dash of crushed red pepper flakes if using. Toss until everything is evenly coated.
• Spread the sausage and vegetables in a single, even layer on the prepared baking sheet, leaving a little space between pieces so they can brown.
• Bake on the middle oven rack for 20 to 25 minutes, stirring once about halfway through, until the vegetables are tender and slightly browned and the sausage is heated through.
• Remove from the oven, garnish with fresh parsley or basil if desired, and serve immediately.
