Though my recipe calls for a less lean meet, I have an eggplant, tomato, and pork casserole that is a favorite cold weather dish and I use tenderloin because it's relatively inexpensive and very easy to cut up for the dish. I start making it in the fall when the eggplants are still producing and the weather has cooled. I serve it with mashed potatoes. This is a recipe I scanned for someone ages ago and I have it in my Flickr account. I landed on this recipe when I was trying to find a way to use as many things from my garden as possible and I had lots of tomatoes and eggplants. It comes from Tess Mallos' The Complete Middle East Cookbook, a book I have given to all of my family members. My mother liked it and years ago gave copies to her sisters (one who is married to a Turkish immigrant who loved these recipes).

The funny thing about this book is that the newer editions are expensive paperback, but I go to Bookfinder.com and I search for the book using "The" in the title (my librarian friends scratch their heads on this one - it should drop out and not affect the search, but that isn't how this works) and I choose "used or out of print" then look for the hardcover editions. I can usually get them for under $10; I just ordered another one for under $5. I keep extra copies to use as gifts. I had a copy at the library where I worked and we had lots of international student employees. Sometimes that book was used as the ice breaker, other times it was used to compare recipes, because Mallos has it broken down by country so the same general recipe appears in different forms several times in the book. I gave that office copy to a co-worker when I retired because though it sometimes was a distraction, the bonding that people do over food is one of the fastest methods I can think of.

BTW: When I have extra eggplants I peel and cut them up and cook and then freeze them, so I always plan for a few for that casserole by cutting them in quarters length-wise, browning all sides, and freezing. Then they're ready for the casserole even out of eggplant season.
