lovewdwdvc is absolutely right!
I also freeze meals. Like tonight I'm making chicken enchiladas I will make 1 pan for tonite and a 2nd pan for the freezer for next month (I just add olives before cooking)
I also freeze meatloaf/meatballs. This trick is a time saver, I make the mixture for meatloaf in my big mixer (less messy fingers) but doubling or tripling the ingredients. Make 1 loaf for that nights dinner, make a 2nd and freeze in plastic and foil wrap. and also roll out meatballs, freeze them on a tray then when frozen place them in a zippy freezer bag.
I do the same w/ lasagne, broccoli rice casserole, quiche.
I also freeze leftover taco meat, spaghetti sauce, chili, etc.
