If your New Years Resolution is to enjoy more grilled cheese sandwiches (that's really a much better and more realistic goal than losing weight anyway), then the first place you should head is Momtastic, where you can learn how to make a new grilled cheese sandwich for every day of the month. These aren't just a matter of using cheddar instead of American either. These sandwiches are each vastly different than one another and the variety of flavors is rather impressive. Personally, I think I'd like to get started on the roasted strawberry, brie and chocolate one followed by the corned beef.
Of course, if your resolution is to lose weight, this list is also a perfect excuse to quit your resolution early.
