Sausage and Peppers Italian-Style

No ratings yet
Sausage and Peppers Italian-Style is a one-skillet dish featuring seared Italian sausage, bell peppers, onions, and tomato sauce simmered together for tender, flavorful results. Searing the sausage first creates a crispy casing and helps retain moisture while the peppers stay tender-crisp during the gentle simmer.

  • Cut peppers uniformly to ensure even cooking and avoid sogginess.
