Cut crust off all slices of bread. Mix all remaining ingredients together in medium sized bowl. Spread cheese mixture evenly over 3 slices of bread and stack slices evenly. Cut the stack into 6 even squares. Once you have finished cutting the entire loaf into layered cheese squares, place squares onto a cookie sheet. Let them harden in the freezer for 15-20 minute Then you can either bake them @ 350 degrees for 10 - 15 minute or put them in a large Ziploc bag and freeze for later use.
