Step 1

Preheat the oven to 400 degrees F. For easy clean up, line a large, rimmed baking sheet with parchment paper.

Step 2

Place the cut sausage, bell peppers, and onions in the center of the pan.

Step 3

Drizzle with the olive oil and red wine vinegar, then sprinkle with the garlic, salt, basil, oregano, black pepper, and red pepper flakes. Toss to combine, then arrange in a single layer.

Step 4

Bake for 25-35 minutes, until the peppers are as tender as you like, tossing once halfway through. Remove from the oven and serve hot.
