Preheat oven to 350. Cut the loaf diagonally one way and then again the other way to make little one inch diamond shaped cuts. Do not slice the bread all the way through.
Take a butter knife and spread about half a cup of the pimento cheese between the slices so that some gets down in to the bread. Spread the rest of the mixture all over the top and crumble the bacon over it. Wrap entire loaf in aluminum foil, bake on 350 for 15 min.
Take bread out of the oven and unwrap the top and broil the bread for 2-4 minutes so that the cheese gets completely melted and the bread is a little brown and crusty.
