In a large mixing bowl, combine the shredded cabbage, shredded carrots, chopped bell pepper, and chopped green onions.

In a separate bowl, whisk together the mayonnaise, ketchup, sweet pickle relish, white vinegar, Worcestershire sauce, garlic powder, onion powder, salt, and black pepper until smooth.

Pour the dressing over the vegetable mixture and toss until well combined. Serve immediately or refrigerate for 30 minutes to allow flavors to meld.
