I freeze everything in glass, foil pans, or freezer bags. The glass is best, but it can be expensive and heavy to have a freezer full of glass. If you have something acidic, it is best to avoid foil. I do have a food saver, and I love the results with that.
I have a bunch of the freezer meals I do in the ddc cookbook, but also google OAMC (once a month cooking) or search oamc on recipezaar.com. Cooking all at once is my favorite way to cook. I usually get a big pack of chicken and a pack of ground turkey, prepare it all, then freeze it. I defrost in a bowl or in the fridge overnight. I have a big monthly menu on the freezer so I know what I need to pull. My biggest problem now is figuring out what to make for the super hot months. Here in TX, we are already getting "too hot to cook" anything. We are having fajitas with pineapple and oranges tonight. Yum!
As for ideas, I check out the companies that do this. Sorry, but I can't think of any of the names right now. They post menus for 1-2 months, and I make my own versions of the stuff they offer. When I am stuck for new ideas, that really helps me come up with something new or weather appropriate.
