There are three of us that eat meals (ds #2 is breastfed) and I don't do the whole once a month thing, but I have been better at just freezing half of what I make. That leaves us enough for one meal and lunch for my dh and I for the next day. Doubling the recipe and using that for several different things (spaghetti sauce can be used in lasagna or a variety of other Italian things, taco meat for taco soup, enchiladas, etc.) is also a time saver for us. I also cook a bunch of ground beef, chicken, and other meat and freeze it in recipe sized portions. I have found that if I have the things that make meals the longest to make (preparing the meat, chopping the veggies, etc.) ready to go it is much easier to put together healthy meals. I also make a list of what I have in the freezer and plan my weeks accordingly. I too use my crock pot a lot, but will double what I make in it and throw half in the freezer. I started doing that with cookies too! It is much harder to eat frozen cookies, but easy to pull one out at a time. By the time it is thawed, one is enough!
I invested in one of the vacuum sealers, which is awesome. The frozen things don't get freezer burned, which was my problem before. Now I can stock up on meat when it is on sale or when we order with one of the local farmers and it stays good for much longer. I know people who have done the once a month thing and it always seems more successful if you have two or three people who do it together. My cousin does it with her mom and they take turns planning menus and get together one Sunday a month and cook cook cook. I think it would be a lot of work to do alone, but with other people it could be much fun.
Has anyone tried the "super suppers" franchise or other similar place? You go make a bunch of stuff, they provide the ingredients and storage containers. We just got one around here and I have heard good things about it. Just curious if any of you mamas have tried it.
