Preheat the oven to 200 degrees C or 390 degrees F. Trim the steaks, brush with the oil and sprinkle with salt and pepper. Heat a frying pan over high heat. Add the steaks and cook for three minutes each side or until well browned.
Remove from the pan. Roll out the pastry on a lightly floured surface until 3mm (1/8 in) thick. Cut 4 x 14cm (51/2 in) rounds for the base and 4 x 16cm (6 in) rounds for the tops.
Line a tray with baking paper and place the four pastry bases on the tray. Top each with a piece of beef and 1/2 tablespoon mustard. Brush the pastry edges with the egg and top with the remaining rounds of pastry. Press the edges to seal and brush the pastry top with the egg. Bake for 20 minutes or until the pastry is golden and the beef is cooked. Serve with a tomato chutney. Serves four.
