- In a saucepan over medium heat, brown the onion in the oil. Add the brown sugar and cook, stirring constantly, for 1 minute. Deglaze with the vinegar. Add the remaining ingredients except the parsley. Season with salt and pepper. Bring to a boil. Cover, reduce the heat and simmer until the vegetables are tender, about 25 minutes. Add the parsley and adjust the seasoning.
- Serve with open-face sausage and paprika sandwiches.
