Place onion, cheese, butter/margarine and eggs in a food processor and process until the onion is very fine.

Add the cornflour and xanthan gum and mix well. The mixture will be very crumbly, so add water until the dough becomes a solid ball. It takes a while, but it does happen!

Remove the dough from the processor and form into 15-16 equal-sized balls. Roll out into circles to approximately 1/4" thick onto a lightly floured work surface (I used parchment paper). Set aside until filling is ready.

Saute the onion in the oil until translucent. Add the rest of the ingredients except for spinach and stir until the beef is browned.

Add water to cover the mixture and allow to cook until no pink remains in the beef.

Just before serving, add in the spinach and allow to wilt.

Preheat oven to 400F.

Place approximately 1 tbs of filling onto one half of the dough circle and fold in half to create a pocket. Press your fingers into the dough to seal it closed.

This will be very crumbly, but allow at least some slits to ensure ventilation during baking.

Transfer to a greased baking pan and bake for 15 minutes.

Enjoy served hot or cold with sour cream, salsa, guacamole or whatever other toppings your tastebuds desire.
