Preheat the pan over medium heat, while you prepare the sandwich.
Generously butter one side of a slice of bread, then place it butter-side-down onto the pan until brown. Add some sweet Gorgonzola cheese. Butter the second slice of bread and place butter-side-up on top of the Gorgonzola. Grill until lightly brown and flip over after two minutes with a spatula. Once the Gorgonzola is melted, place it in a dish with some ketchup, and enjoy!!
