In a large mixing bowl, combine the shredded green cabbage, diced avocado, cherry tomatoes, red onion, and chopped cilantro.
In a small bowl, whisk together the olive oil, apple cider vinegar, Dijon mustard, salt, and pepper to create the dressing.
Pour the dressing over the cabbage mixture and toss gently until all the ingredients are well coated.
Taste and adjust the seasoning if needed.
If desired, sprinkle feta cheese and pumpkin seeds on top for added flavor and crunch.
Serve immediately or refrigerate for 30 minutes to allow the flavors to meld.
