Napa cabbage (sweeter and tender) or red (regular green is too bitter)
Red onion - sliced really thin to break the cells down
Raw, unfiltered apple cider vinegar
Gluten-free Dijon mustard (I like Whole Foods brand)
Fresh black and/or white pepper
Unrefined sea salt (The salt will draw the water out and let the the apple cider in.)
Extra virgin olive oil
Pinch of stevia (Stevita or Kal brands) - if you like it a little sweet.
Mix all ingredients, cover and set aside for a few hours, and then toss it again before eating.
