Preheat your oven to 350 degrees Fahrenheit.
Heat the 2 tablespoons of olive oil in a large skillet over medium heat and add the onion and garlic. Cook, stirring frequently, for a 2 - 3 minutes until the onion is soft and translucent being careful not to burn the garlic.
Add in the oregano, cinnamon, cumin and paprika. Stir and cook for approximately 1 minute and then add the tomato paste. Cook for an additional minute, stirring continuously.
Add in the ground beef, and add the water.
Cook, stirring occasionally, until the meat is cooked through and water has evaporated. Be sure to break up the ground beef as it cooks as you don't want very large pieces.
Once the meat is cooked, season with the salt and pepper and add in the Metaxa or red wine if using. Cook for an additional minute and then remove from the heat and allow to cool.
Once your meat filling has cooled, it is time to start assembling the kreatopitakia.
Lay your sheets of filo out onto a cutting board and cut a 3 inch wide strip (there will be many layers to this strip). Set aside and wrap up the remaining filo well so that it does not dry out.
Then, take one layer of filo and brush with some olive oil. Place another layer of filo on top of that one and brush that as well with olive oil.
Place approximately 1 tablespoon of filling on the bottom of the two-layered strip of filo and begin to fold over so that you end up with a triangle shape (see photos above, or attached video)
Once your triangle is formed, transfer to a parchment paper lined baking tray and repeat until you have used up all the filling.
Brush the tops of your triangles with some olive oil and bake in the middle rack of your oven for approximately 20 minutes, until golden brown and crispy.
Remove from baking tray and allow to cool on a rack.
