coz it's that good! it has so many flavors and variations, it's hard to find someone who wouldn't love one or another type of a grilled cheese sarnie.
Prosciutto , apple , onion and cheese, that's my favorite combo!
I love a little tangy apple in it to set the cheese off, something about it, it's sooo good.
Don't overdo the prosciutto, you want it there just for the variation in flavor, not to add too much saltiness.
here it is:
5 grain bread
thin slice of onion
slice or two of apple, I prefer sour kind,like Rennet
4 thick slices of full fat cow's milk cheese to your liking
a strip or two of prosciutto
stack,fry in butter (if you want to reduce fat, use PAM or any other spray oil straight on the bread)
p.s if you find that raw apples and onions are too much for you, feel free to caramelize them,that works too ;)
