This crust-less quiche makes regular appearances in our house. It's so easy to make, and tastes so good. It also freezes well, and I'll often freeze portions wrapped in plastic wrap for quick meals or snacks. Over the years I've served this as breakfast, brunch, lunch, and dinner, and it's been fantastic every time.
I've tried several different types of frozen hash browns, and prefer the Ore Ida brand Country Style. The generic store brand I tried was too thinly shredded to be noticeable in the finished quiche, and the Ore Ida Southern Style (little cubes) were too big.
