If you have a panini press, then you should give yourself a round of applause. After all, you're the proud owner of the greatest upgrade to grilled cheese ever invented. Because the panini press weighs down bread as it cooks, the recipe below for cheese panini is crispier and meltier than a standard grilled cheese. The other nice thing about a panini press? Because it's electric, it provides even heating and cooks a sandwich in a fraction of the time.
If you don't have a press, never fear. You can mimic this recipe by using a smaller pan as a weight. After setting the sandwich in a large cast-iron skillet, cover the bottom of a smaller pan with aluminum foil. Set the smaller pan on the sandwich to press it down. It will take a bit longer, but the end result will be similar.
