I made this after craving vegetables and looking for something that I could eat soon after getting home from work without too much work (I did steps 2-4 the night before then threw it in the crock pot the next morning).
I left out the mushrooms because I'm not a fan, but otherwise followed the directions. I saw tips of cubing the eggplant prior to roasting, which I think would make it a lot less messy. When it was finished it was good, but I felt that it was missing something. It took me a while to figure out, but now seems so obvious, that missing ingredient is cheese! The only cheese I had on hand were grated parm and cheddar, so I opted for the parm and it was immensely better. I imagine mozzarella would be ideal, so when I reheat it (I plan on freezing the batch), I'll be sure to have some.
