I saw a program on TV about this 2-3 months ago. The key to making it work is in the initial planning, according to them. Things like:
You all need to sit down and discuss likes and dislikes, food allergies, etc.
Are you preparing microwaveable heat-n-eat meals or meals that need to be cooked in the oven? This will have some impact on packaging.
With those items worked out ... then you can start menu planning.
You're no longer cooking for 2 - you're cooking for 14 people! You may need to pick up some new cookware to handle the volume. I would suggest checking out a restaurant supply store ... for example, you can get a full size 4-inch deep Stainless Steel pan for about $17 which will hold 15 approx. 4"x4" servings of lasagana. Do measure the inside of your oven to see what size pans you can use before buying them!
A full size pan woud fit in my old gas oven - but will not fit in my new electric oven.
Here are some Freezer Meal sites
that will give you info on what will and will not freeze well, and more recipes than you can shake a stick at! Many things can be fully cooked before freezing - just walk down the "TV Dinner" frozen food aisle of your grocery store and look at the variety available.
