Empanadas IV - Vegetarian Picadillo

These are very similar (if not exactly the same) to Empanadas I but I feel you need a refresher. These are fairly time consuming to make as the dough is a bitch but it is all worth it in the end. Let's begin:
Dice up a few red potatoes into very small chunks and saute them with some onion and garlic. Once softened add your fake ground beef and cook until heated through. Remove from heat and toss in a shitload of diced green olives (I like the ones with the jalapeno centers) and two tomatoes (seeded and gutted). "All I have are black olives. Can I use those?" Don't be stupid, jackass. Set aside to cool.
Make a savory pie dough (i.e. no sugar, genius) and quarter it. Use the same technique as Empanadas I. Place on a pizza stone on the lowest rack and bake at 425 deg for about 20 min. Eat it.
