I had a hard-on for mozzarella at one point.
For several months, I would use it in place of whatever cheese I would normally use. I melted it on my burgers, made queso with it, grilled-cheese sandwiches, nachos, etc. My experience with different cheeses isn't all that extensive, but I liked the mozzarella for one thing because it melts better than any other cheese I know of. I also found out it is a damn versatile cheese.
I got burnt out on it eventually, and now save using it for piling on top of a homemade pizza.
