Preheat the oven to 400ºF.
Cook the sweet potatoes until soft*, slice in half, and scoop out the flesh into a medium mixing bowl. Combine with cauliflower rice, diced green chiles, eggs, flour, salt, and pepper until smooth. Grease the cast iron skillet or baking dish with your cooking fat of choice, then scoop the crust mixture into the dish~ spreading evenly over the top. Bake for 25 to 30 minutes, or until the edges begin to brown.
Meanwhile, in a large pan, sauté the ground beef with spices until browned.
In a small bowl, combine the sauce ingredients and set to the side. Feel free to add a little water or broth if you prefer a thinner sauce.
Remove the crust from the oven, then top with the spiced ground beef, followed by the red sauce. Top with a little shredded grass-fed cheese if you like, then return to the oven and bake for 10 more minutes to heat through (the sauce will begin to bubble).
Allow your "Tamale Pie" to cool for a few minutes before slicing & serving~ topped with garnish of your choice. Enjoy!
