I don't remember where I got this recipe, but it sure is delicious! To get the perfect grilled cheese every time, you should start by heating your skillet to low. Once you build your sandwich, leave the skillet on low and cover with a lid or foil. Cook for a couple of minutes to let the cheese get gooey and you fillings get warm. Then remove the lid/foil and turn up heat, flipping your sandwich until it is perfectly toasted. Yum!
