Many of my favorite recipes were originally printed on the packages of food products I purchased over the years. Some were found in women's magazines, and some were given to me by friends. These recipes were copied and recopied so many times  that it is now almost impossible to know where some of them originated. 

The Biscuit Mix box had the recipes for the "Impossible Pies" and the Pillsbury Flour bag had the recipes for the "Crazy Crust Dinners" which were family favorites. Additional Impossible Quiche recipes are on the Internet.
