This recipe for lasagna soup is a fantastic way to make use of leftover parmigiano-reggiano rinds. The recipe is written for one serving, but its easy to scale up if you have a lot of cheese rinds stashed away. There are fancier preparations out there for parmigiano broth, but youll be amazed at how much flavor you can extract from the rinds alone. This soup would be great with ground pork or sausageor mushrooms for a vegetarian version. The nutmeg recalls a lasagna made with bechamel and adds depth, while cooking the noodles in the broth adds body. It all adds up to a hearty delicious soup thats a lot less work than a whole lasagna.
