First, gather all of your ingredients. Have flax chips already made or purchased. Preheat oven to 350 degrees. This picture was from my flaxseed chip recipe after they were made.
Cook the 2 lbs of ground beef with the mushrooms and onion. Add all of the spices including the salt. You want to sautee for about 20-30 minutes, or until the ground beef is cooked through thoroughly. In the meantime, also take your 24 oz of cauliflower rice and cook that in a pan into it is unfrozen.
After the meat is and cauliflower rice is done, it is time to go ahead and layer it into the pan. First, you want to layer the cauliflower rice in the pan, and then place the beef mixture on top of it.
Lastly, go ahead and break the flax crackers up and proceed to layer them on top of the mixture. Then place the cheese on top of this and you are ready to place in the oven! Bake for at least 15-20 minutes.
After it is done baking, let it cool for about 5 minutes. Then proceed to layer the sour cream on top with toppings. The ones I chose were, cilantro, black olives, avocado, and lettuce. You can choose any that you like, just make sure they are keto-friendly.
Serve and enjoy!
