Easy and pretty - parmesan disks or wafers. To make them,
heat a non-stick skillet over medium-high heat. Take about a 1/4 cup of grated parmesan and sprinkle it in the pan to make a rough circle shape. When it begins to bubble and melt together, remove it from the heat to cool for a bit, then remove from the pan with a spatula and set on a flat surface to cool completely. Makes a lacy disk that is delicious as a garnish to a green salad.
You can also form them into shapes while still warm - I've seen them draped over a small bowl to make a parmesan bowl to serve salad in, or rolled into cones. If you want to attempt shapes other than the flat disks, I recommend practicing beforehand - I've not had great luck with anything beyond the basic disks. They are yummy!
