Preheat oven to 375ºF (190ºC).
Mix the cauliflower, Brussels sprouts, coconut milk, broth, garlic, and half of the cheese in a large bowl. Season with salt and pepper.
Add the mixture into a casserole dish and top with the pork rinds. Bake for 50 minutes or until the sauce thickens and bubbles and the pork rinds brown.
Sprinkle the remaining cheese on top of the casserole and let cool for ten minutes before serving. Enjoy!
