Although these pickled onions are tasty on their own, we also liked them on the Roast Pork Sandwiches. You can prepare them up to two days in advance.
2 cups red wine vinegar
1 cup sugar
1/4 teaspoon salt
4 cups thinly vertically sliced red onion (about 2 large)
How to Make It
Combine vinegar, sugar, and salt in a small saucepan; cook over medium-high heat until sugar dissolves, stirring frequently. Pour vinegar mixture over onion; let stand 1 hour, stirring occasionally. Chill. Drain before serving.
