For an extra layer of flavor, consider adding a pinch of smoked paprika to the vegetable mixture while it cooks. Serve with crusty bread for soaking up the delicious sauce and runny egg yolk. This stew can be made ahead of time and reheated. The flavors will actually deepen overnight! Feel free to add other vegetables to the stew, such as eggplant or potatoes, depending on your preference and what's in season.
