I do understand what you are going through...
times like these it is nice to have a meal in the freezer, ready to cook, or at least basic ingredients prepped so you can do a quick meal.
I like to have ground beef already cooked in the freezer, so all I have to do is pull it out, thaw it, and make something... sloppy joes, quick casserole, a beef and noodles dish, something like that.
Long ago, when I made meatloaf, (I haven't for a long time), I would use 2 lbs, and make 2 loaves. (I don't like using a pan, I just shape it myself and put it on a cooking rack in a pan.. I don't like it soaking in the grease the entire time it cooks.) That way, we would eat one meatloaf for dinner, and I would freeze the other, for a relatively quick meal when I need one handy.
I also frequently have chicken cooked and chopped in the freezer, also, in meal size bags. That can be the basis of a quick meal, also.
I realize sometimes it is hard to get it together and create the meal.... maybe these suggestions will help!
Also, there is nothing wrong with having sandwiches for dinner.... just throw a blanket on the floor and have a "living room picnic" ... fun!
