Our friends, the O'Brien's, shared this with us after we all raved about it. Great to have for football. This recipe calls for several layers but it's versatile enough to have as many as you want. I use more prepared horseradish than the recipe calls for because we love the "tanginess" it gives the sandwich. I also use deli meats and ask them to slice it for me. Also, the directions call for cooking the sandwich for 10 to 15 minutes but in my oven, I have to turn the temperature down to 350°F and leave in oven for about 30 minutes.
