Lorraine Wallace's Quick Chicken and Vegetable Quiche

Preheat oven to 425°F (220°C).

Roll out refrigerated pie crust and line a 9- or 10-inch pie or quiche plate. Prick dough all over with the tines of a fork and crimp the edges between your thumb and forefinger so they form a pattern along the top edge of the plate. Place a piece of aluminum foil into tart shell and weight with pie weights, uncooked rice, or dried beans. Prebake shell until crisp, 10 to 12 minutes.

Meanwhile, heat oil in a large skillet over medium heat. Add onions and sprinkle with salt. Cook, stirring, until onions are wilted and translucent, about 5 minutes. Reduce heat and continue to cook, stirring occasionally, until onions have softened completely and are lightly caramelized, another 20 minutes. Add asparagus to the skillet and toss until slightly cooked, about 3 minutes. Add chicken and toss together with asparagus and onions until heated through, about 3 minutes.

Reduce the oven temperature to 375°F (190°C).

In a large measuring cup, whisk eggs and milk together and season with salt and pepper.

Place the prebaked pie crust on a baking sheet to prevent any egg mixture from spilling into the oven and place meat-vegetable mixture into crust, top with grated cheese, and then carefully pour over egg-milk mixture. Bake for 35 minutes, or until top begins to brown and custard is almost set in the middle. Allow to stand for 10 minutes before slicing and serving.
