Heat coconut oil in a frying pan, add shallot and fry for 2 minutes. Add minced beef and cook for 3-4 minutes. Stir in salsa, chili flakes, garlic powder, salt and pepper as well as taco seasoning (if using). Cook on low for 10-12 minutes.
Preheat the oven to 400 F. Line a baking tray with parchment paper. Mix cheddar cheese and mozzarella in a bowl and divide this mixture into four parts. Place shells on the baking tray and bake for 5-7 minutes.
Let cool for a minute. Add 2 tbsp of beef mixture on each shell and roll quickly. Serve immediately, topped with sour cream (optional)

Notes
You can use ground chicken or pork in the place of beef. Add extra herbs and spices of your choice when seasoning the meat.
