In a large bowl, whisk the vinegar, sugar, mayonnaise, mustard and poppy seeds. While whisking, add the olive oil in a steady stream to form an emulsion. Season with salt and pepper.
Fold in the green and red cabbage, red onion and cilantro. Season with salt and pepper as needed. Serve immediately or refrigerate in an airtight container for up to 1 day.
