Heat a pan with your oil. Brown your beef, then add your diced veggies, ketchup (or tomato sauce), Worcestershire, chili powder, cumin, cinnamon, salt, and pepper. Cook and gently stir until the vegetables are tender, then add any frozen vegetables. Allow your beef filling to simmer on low and covered while preparing your dough. Remove from heat for a few minutes before filling your dough.
Preheat oven to 375 degrees
In a food processor, combine flour, salt, and cubed cold butter and pulse until combined. Add your egg, water, and sourdough discard, and pulse until it comes together. Remove your dough and form a dough ball with your hands.
Transfer to a lightly floured surface.
Lightly dust your dough with flour and cover with parchment paper. Begin rolling out your dough into a rectangle.
Using a large round pastry cutter, large bowl, or large cup, make 6-8 inch circles with your dough. I often roll the dough out a little more once my circles are made.
Begin to spoon 1-2 tablespoons of your meat filling into your premade empanada dough. Fold your dough over and seal the edges by pressing a fork into the dough or by twisting the dough together from one end to the other. Finally, brush the tops of the empanadas with egg wash. Continue to roll out your dough and repeat this process with the remaining dough.
Place your baking tray with sourdough empanadas in your preheated oven and bake for 30-35 minutes or until golden brown. Cool for 5-10 minutes before serving – insides will still be hot.
