In a large skillet, brown ground beef and remove any fat that renders as it cooks. Add in your go-to keto taco seasoning and water. Bring it to a boil, reduce the heat and let it simmer for a few minutes.
Push the taco meat over to the side of the skillet and add the riced cauliflower, cilantro, and salt in the open space. Cook the cauliflower for 3 to 4 minutes, then push it to the side to make room for the scrambled egg. If you don't have a large enough skillet, grab a separate pan to scramble the eggs.
Melt ghee and pour in the beaten egg. Whisk the egg and shake the skillet as it cooks to break up the curd. Once the egg scrambles to your liking, mix it in with the rest of the dish. Season with salt and pepper to taste.
