Preheat the oven to 350ºF.
Cut steak and veggies into bite-sized cubes. Mix all ingredients in a bowl with olive oil.
Combine flour, lard, and salt using a pastry blender until crumbly. Set aside.
To make each dough pocket, combine 1 cup of crumble with 3 Tbsp of milk with a fork or your hands. Roll out with extra flour until it is about 12 inches in diameter.
Put 1 cup of the meat and veggie filling on one side of the pocket and fold the other half over the filling.
Fold and pinch the edges of the pocket to seal in the filling and place on a baking sheet. Bake for 1 hour. Work in batches if necessary.
Allow pasties to cool and serve with ketchup. These can be frozen and reheated.
