Divide the pie filling amongst four 5” ramkins
Lightly oil the top edge and inside edge of the ramkin with a little olive oil
Divide the biscuit topping mixture into four equal parts
Spread the biscuit dough into a circular disc with your hands and place on top of the filling inside of the ramkin
Place the ramkins on a baking sheet and bake for 25 minutes or until biscuit topping is golden and the pot pie inside mixture is bubbling
Notes
Left over pot pies can stay in ramkins and be wrapped in aluminum foil and stored in the refrigerator. To reheat unwrap the pot pie and place the aluminum foil lightly over the pie crust. Cook in a 400°F oven for about 15 - 20 minutes until warm.
