When I was a boy, one of my favorite meals was what my mom called, "Clean out the Icebox." It might be soup, or a casserole, baked or fried, but I always liked it. My older siblings have somewhat different recollections.
What's "Clean out the Icebox"? Just what it sounds like. Whatever leftovers mom found that could, reasonably (to her) be combined.
Yesterday I made my own attempt. I had some leftover pot roast, as well as a little bit of the ragu I made weeks ago. (It had been frozen and thawed in the meantime.) Plus I had some vegetables that were wilting, and some leftover beef broth.
So, I chopped up the roast and the vegetables left with it. I dumped in the broth; I chopped up some carrots and celery from the fridge, and set all that on the stove to simmer. At some point, I added some salt, pepper, and garlic; later, a bay leaf; and later, a handful of broken up spaghetti (because I had neither barley nor noodles). I simmered it some more, and had some last night for dinner. It was helped by some Parmesan cheese. Here's today's lunch:
Yes, it does rather taste like what mom would have cooked!
Oh, and FYI, this is an icebox. (There are pictures at the link.) We actually had one, growing up, but we also had an electric refrigerator, so mom used the icebox to store other things. My clever mom sawed off the bottom of it, so that it was just tall enough for the top to be a great work area. I think my brother has that now.
