This is a great recipe for a crockpot. In the morning, throw everything, except the kielbasa and frozen peas, into the slow cooker. When you get home in the evening, stir in the final ingredients, and dinner will be ready by the time the table is set. A loaf of crusty bread turns this comforting soup into a weeknight feast.
2 tablespoons extra-virgin olive oil, plus more for drizzling
