From Rachael Ray's magazine, link here.
This wasn't really something I liked. I didn't like the inside gunk. I did, however, learn some new tricks. I learned a way to make ravioli without having to make pasta. I learned how to roast garlic.
I also found that it took me nearly 30 minutes to food process everything I was supposed to for this recipe, so if you try it, process in batches then stir it all together OR chop your shrooms a little bit.
