Well done for planning ahead :) And congratulations on your pregnancy.
I too am expecting # 2 and I have a 3 year old, Jayson will be born around 12/21/09. I recently had to go back to work fulltime and I am high risk for this pregnancy so I have to lie down on my left side for an hour after work each night.. this makes conventional cooking virtually impossible.
I spent a bit of money and invested in some pyrex casserole dishes. I buy the ones that are about $5 each at walmart.
I do things a bit differently to others, instead of preping food for a whole month. I pick one meal a week and on a sunday I cook 4 weeks worth of that meal. Right now I have about 30 meals in my freezer.
I prefer the pyrex because I can put them in the oven when I get home, turn the oven on and let them thaw/reheat for 30 minutes. They are reuseable. When I have 4 empties i cook a new batch of food. I usually leave them in the refrigerator overnight. I sometimes end up with 2 days food in a container so we eat the same meal twice in one week. Thank goodness my husband is not a picky eater and I can do this. It has been a huge help. Because I can tell him to pull X out of the freezer and he just has to put it in the oven for x minutes. Make sure you only turn on the oven once the pyrex is in it. Then it will warm up the glass slowly.
Meal ideas: chicken a la king, spaghetti and meat sauce, beef stew, chicken alfredo, shepherds pie, lasagne, curry 'n rice, soups, etc. I sneak veggies into all my meals by cooking them and pureeing them into the sauce... even my chicken alfredo has veggies. Almost everything is freezable, I have yet to find something that wasn't but be sure to check online as said below for what works and what doesn't. I cook my rice and pasta and add them,I just make sure they are barely cooked before adding them they continue o cook a little as you defrost.
I hope this helps.
