All you do is add an ingredient to the outside of the sandwich to make it super crispy and a little cheesier.
Simply add a tablespoon of grated Parmesan to a tablespoon of butter (or more if you're so inclined – the recipe on brit.co calls for two tablespoons of each, but that might be a bit much for some)
Then you spread the mixture on both slices of bread – these will be the outside of your sandwich.
Then fill your sandwich as you normally would and cook as usual. You'll get a super crispy and extra tasty grilled cheese toastie!
Looks YUM !!
But not quite on my list of foods that I partake in.... possibly in my younger age ..... like some 70 years ago :)
