Hot Pockets are nothing new, original, or even modern. They have much in common with many french "individual pie" dishes which featured various ingredients stuffed into small shells of pie crust or puff pastry (ok, so maybe you coudn't get them in "Ham'n'cheese" or "pepperoni pizza" varieties). Indeed a dish which I feel is superior to a hot pocket can easily be made at home using store bought puff pastry ( a smaller version of my own Lamb in Pastry ). Simply cook up a filling, seal it in an envelope of puff pastry and bake at 400 degrees for 10-20 minutes. Not as convenient or as cheap as a Hot Pocket, but much better tasting.
