I see what you did wrong here, you needed to make dough and kneed and fold it for like 30 mins, then let it rest over night. Then you bake it at 325 for 40 mins or until the dough in the center is nice and flaky, then you need to go to your local pig farm, maybe a 20-130 min drive, get the juiciest hog you can find, kill it, then take to your nearest butcher. Then take it and smoke it for 2-3 days with applewood, you'll get the sweetness of the wood without any of the char. Then slice it with your countertop deli slicer. Then you buy your cheese from an auction house in Italy and have it imported, break the wheel with your dedicated cheese wheel cutting knifes (also found on my store) assemble the sandwich and grill it until golden brown. Then you have a better grilled cheese, hope that helped!
