Step 1

Heat oven to 400°F. Place pie crust in 9-inch glass pie plate as directed on box for One-Crust Filled Pie. DO NOT PRICK CRUST. Bake 8 to 10 minutes or just until edge begins to brown (if crust puffs up in center, gently push down with back of wooden spoon).

Step 2

Meanwhile, in medium bowl, beat eggs, milk, flour and Parmesan cheese with wire whisk until well blended.

Step 3

Layer ham, tomato, onions and Cheddar cheese in partially baked crust. Pour egg mixture over layers.

Step 4

Cover crust edge with strips of foil to prevent excessive browning; bake 25 to 35 minutes or until golden brown and knife inserted in center comes out clean. Let stand 10 minutes before serving.
