Prosperity Sandwich

I got a craving for a Prosperity Sandwich. They used to serve one at the Sheraton WestPort when I worked there as a waitress one million years ago. As I remember, it involved toast layered with ham and turkey, smothered with a mellow, creamy cheese sauce, topped with 2 slices of bacon and then heated. I looked online, and even though I went several pages into the search, I found only fond reminisces. It must be a St. Louis sandwich because the only references I found to it where about restuarants here. My daughter Grace has been on an "out of the ordinary" sandwich kick lately (she has been taking a fluffer nutter in her lunch) so she encouraged me to make it. I took two oven proof dishes and lined them with toasted bread. I used a whole grain wheat because that is what I had. I then layered Honey Roasted turkey from the Deli and some leftover Easter ham. I made a cheese sauce by cooking some flour and butter. I then added about a cup of evaporated milk. I let that cook and thicken a few minutes. I tossed in some cheese from the cheese drawer - some shredded cheddar and then a handful of mozzarella. I ladled the cheese sauce over the meats and toasts and sprinkled it with a couple strips of bacon I had chopped and thrown in the microwave to cook. I heated it in a 350 degree over for 15 minutes. It turned out very tasty. It was not the creamy smooth sauce that I remember but my guess is the original version may have been made with Velveeta or American. It was very smooth, not stringy and clingy like the cheddar suace.
