So I went to DC over New Years to visit Kate, and during one of my hangover recovery periods, I watched a whole bunch of Good Eats on my computer. One of the episodes was Egg Files II - Man with a Flan and Alton made quiche, which he dubbed refrigerator pie. It was super easy. I took a store-bought pie crust (yes, I know, I'm lazy) and then put a royale mixture in it and then stuff.
1 pie crust
1 c heavy cream
2 pinches salt
Preheat oven to 350. Beat eggs and cream and then beat in the salt. Put your fillings in, but leave open spaces for the royale mixture to go. I used mushrooms sauteed in butter and garlic salt (I ran out of garlic. :( ), broccoli that I had pre-cooked a bit, and some white cheddar cheese with herbs. It has a name. I don't really remember it, though.
Don't fill everything up to the top. Bake for ~45 minutes, or until the filling is set to the consistency of jello.
It turned out really well. I was surprised by that. I had enough stuff left over to make flan, which actually seemed rather easy to make, but I don't own ramekins and upon further reflection hate flan, so I decided against it.
