This makes a nice change from stew, although it's essentially just stew in some pastry!
I basically made a beef stew for two, using two steaks, an onion, 12 mushrooms, a cup of beef stock and a tablespoon of tomato paste. I cooked it for a couple of hours until the steak was tender, then put it inside some store-bought pastry crust. Brush with some milk, bake until golden. Serve with some nice steamed potatoes and peas. Enjoy!
