I've already done a few things since we have a deep freezer and you can put stuff in there for up to a year. We bought a side of beef a while back and that is taking up A LOT of space with the 3 whole turkeys we have in there, so I'm getting nervous that I may not be able to plan too far ahead. So far I have 1 big gallon ziplocs ready with a turkey with wild rice soup from Thanksgiving. I also have 2 casseroles in there. Pete asked me not to fill it, which is problematic with the "nesting/planing" stage I appear to be in. I also froze a ton of fresh corn this summer and then partitions that into 1 cup servings, but it looks like we've eaten a lot of that, oops!
What I did last time was to make a HUGE batch of meatballs, bake them and then freeze them on cookies sheets. Then you can put the frozen meatballs into a big ziploc and only take out what you need because they are not frozen as a giant mass.
I make homemade tomato sauce and there is always a little extra. So, I freeze the extra in a freezer jam jar. The smaller jars seem to make a 1/2 serving for our family. Since I've been freezing that every time I make the sauce, I have about 1/2 dozen of those. Meatball sandwiches are very tasty, for some reason I liked those postpartum.
Meatloafs in a muffin tin. Line the tin with parchment, freeze it uncooked and then pop them out like ice cubes. When you want to make them, you pop them back into the muffin tin to defrost and then cook. This one assumes you are buying non-frozen meat, though. If I use what we have, mine will need to be cooked before I freeze them since our beef is frozen.
I am tempted to try the parchment/pop it out frozen on some pot pies. My MIL apparently used to make regular pies and freeze then, pop them out of the pie plate and wrap and store frozen solid. Then when she wanted a pie, you can bake from frozen, so she would just pop it into her pie plate and bake one. With my glass pie plates, I think I'd either have to grease it or use parchment to get it out of the plate once it is frozen solid, but I think that has got to work for some pot pies.
I am tempted to pick up some larger freezer jars and go soup crazy. Those are easy to reheat during the day.
Calzones.... Mmmm.... I may have to do that one.
