This makes two hearty Italian style pasta casseroles with beef and spinach for very little money and makes good use of ingredients you might have lying around your house. This comes from my Aunt's recipe collection, updated a bit for my tastes. She had originally clipped this from an article in Family Circle in 1973. I wanted to share the story behind this recipe as well as the recipe itself. Basically, a mom of six children had, on the spur of the moment, decided to invite guests over for supper on a Sunday. Apparently, no stores were open on Sundays, so she was unable to buy any ingredients and was faced with only using her meager household staples, and relied on her Italian family background for inspiration. This was what she created. This makes two big casseroles, one you can eat now, and one you may freeze and reheat later if you are not having a bunch of guests over. I think if you don't have any spinach, you could substitute another veggie like roasted red peppers, sauteed mushrooms...really whatever you have handy is the point here. Also, when you make this...you might say "this could use some more cheese"...go ahead and use extra cheese if you want, melting some on top during the last 5-10 minutes of baking.
