the perfect way to make one, in my opinion, is to spread the outside of bread with softened butter, and then make the sandwich. wrap it in foil, and stick it in the oven at about 250 degrees. when the cheese is all melted, then open the foil and turn the oven on broil. the bread will toast in about 15 seconds, so watch it carefully. then flip it. this way, the bread will be buttery, evenly toasted and crisp, the cheese thorougly melted and gooey…YUM!
