Preheat the oven to 350 degrees.
In a bowl, combine the beef, coconut flour, oregano, garlic powder, and salt. Mix well with your hands.
In a large oven-safe skillet, heat the oil over medium-high heat.
Carefully press the beef mixture into the bottom of the skillet to create a ½-inch-thick “crust.” Cook until golden brown on the bottom, for about 3 minutes.
Using a large spatula, carefully flip the crust, and cook for 3 minutes. Remove from the heat.
Top the crust with the sauce, tomato, cheese, olives, and basil.
Transfer the pan to the oven, and bake until the cheese has melted and the toppings are warm, for 7 to 9 minutes. Remove from the oven.
