In a large saucepan, fry the onion slices in the butter/olive oil mixture until their volume is reduced by about half, do not brown. You may add water, a teaspoon at a time to keep them from sticking to the bottom of the pan.
Add 2 Tablespoons paprika to the onions and mix well. If using ground beef, cook lightly in another pan and break up any chunks. Drain off accumulated fat before adding to the onion mixture. If using a meat substitute, it is not necessary to drain off any fat. Simply add it to the onions.
Dilute the flour in 1/2 cup cold water, mix well and add to the meat and onion mixture. And cook for about 5 minutes. If the mixture seems thick, add some water or broth, but you do not want the mixture to be watery.
You can add the raisins and green olives at this point (which I like to do) or add a few raisins and olives to each empanada as you make them. There will probably be enough mixture to make about 24 empanadas.
Let the meat mixture cool about 1/2 hour before assembling the empanadas. Into each disc of dough (recipe to follow), place about 1/8 of a wedge of hard-boiled egg, 2-3 teaspoons of Pino, and raisins and olives if you have not already added them. Fold over the disc and seal the edges by moistening with water, then folding the pastry along the edge.
Place on a cookie sheet with a non-stick mat or parchment paper. Brush with an egg mixed with 1 teaspoon of water. Bake in a 400 degree F oven for 15-20 minutes until brown on top.
