I served this for Christmas with a roasted beef tenderloin. It was absolutely fantastic! The seasonings were wonderful and the recipe was very easy to make. The only thing I changed was that I did not use any breadcrumbs. Instead, I used some fine grain bulgur for meatballs in the body of the dish and garnished with chopped green onions. Also, after I made it something told be to look again at the cheese package, and sure enough, I used the wrong cheese. I used Monterrey Jack by mistake. So, the recipe is versatile as well! I used only shiitake mushrooms. Will definitely be making this again! Thanks for posting.
