I find that the food I want to cook now, isn't the food we'll want to eat in opposite seasons! However, I did still fill the freezer with about 15 dinners or so, knowing that'd we'd likely get 5 dinners from friends/family in the week or two after baby was born, and with leftovers & take out, we'd get through the first month. It worked more or less. A list on the fridge of important groceries, and quick meal ideas was helpful -- not only for DH to prepare, but for me to prepare quickly w/o having to think!
I'm going to make enchiladas, chili, lasagna rolls (all the fillings of lasagna, but you roll up the noodles -- easier to serve/portion, plus they fit in smaller pans), mock-shepherds pie, some veggie pot-pies, curried chickpeas & cauliflower. As you can see, most of my 'feed the freezer food' is fall/winter comfort food! In summer, I really want to eat salads. Lots of salads, and simple wraps/sandwiches, which just don't freeze well -- fake-tuna-salad (made with chickpeas, and tasting nothing like tuna salad!), egg salad, several varieties of quinoa salads, greek salad, strawberry/spinach salads ... sadly, not easy to make in advance, store or freeze. Fortunately, quick and easy to make.
I do tend to just double cook things a couple times a week, and freeze the extra. I buy the disposable tin w/ cardboard lid containers for stocking the freezer -- I don't have enough lidded glass to leave them in my freezer for months, and I want things to be able to go straight to the oven -- so no plastic/baggies. I can write on the lids time/temp/content/notes. Before DS was born I made a list on the front of the freezer and added to it every time I put a meal in, I forgo to do this before DD was born, so I was always rummaging through the pans to see what was left!
We also eat pizza once a week, which DH does most of the work to prepare, and fajitas once a week or so, which he can do quickly on his own. I may fry, season & freeze onions/peppers, so that part will be ready - aside from that it's just grabbing things from the fridge & heating up beans & rice (which are always on hand).
Breakfast food is what I always forget about actually stocking up on. I will do better this time! Muffins, banana bread, quick yummy things, maybe frozen in 'variety packs' where I can thaw a bag once a week or something.
