Preheat oven to 350°F.

Heat oil in a saute pan over medium heat and add the onion and Serrano pepper. Saute for five minutes, then add the ground beef.

Once the beef is mostly browned, add garlic and spices and stir. Next, add apple and sweet potato. Saute for 5 minutes, or until the vegetables/fruit have softened.

In a large bowl, combine the almond and coconut flours. Then add the eggs and chicken broth and mix well. Pour the beef mixture into the bowl, mix well, then pour the batter into a casserole dish.

Bake at 350°F for 45 minutes to 1 hour, keeping an eye on the dish to make sure the top doesn’t burn.
