1 (16-ounce) package tricolor mini sweet peppers, thinly sliced into rings
½ cup thinly sliced celery
½ cup thinly sliced Vidalia or other sweet onion
1½ cups shredded carrots
1½ cups shredded red cabbage
Instructions
In a large bowl, whisk together vinegar, sugar, salt, mustard seeds, black pepper, and red pepper until sugar is dissolved; gradually whisk in oil until well combined.
Stir green cabbage, sweet peppers, celery, and onion into vinegar mixture until well combined. Cover and refrigerate, stirring occasionally, for 12 hours.
Just before serving, stir in carrot and red cabbage.
Notes
The carrot and red cabbage are added just before serving to preserve their crunchy texture and to keep their color from bleeding into the rest of the slaw.
