Combine all ingredients in a mixing bowl until a cohesive dough forms. If the dough is too sticky, gradually add more flour, and if it is too dry, incorporate additional milk until the desired consistency is reached.
Press the dough evenly into a pie pan, ensuring it takes the shape of the dish, covering the bottom and sides.
Bake at 375°F (190°C) for 12 minutes, or until lightly golden.
