First I would like to suggest a DOULA!!!!! Not only are there birth doulas (which I wouldn't even consider going without) but there are also post partum doulas who can come and help you out in any way you need--including preparing meals.

Now, if you're going to put meat into something, I, personally would absolutely make sure that is cooked first.
Any casserole or cassarole (depending on how YOU want to spell that--hehehe) would be great.
Again, I, personally, would heat in up in the regular oven instead of a microwave. Sure, it takes 30 or so minutes, but tastes much better. (to me)
Here's a really easy recipe:
two cans of chili
one can cream of mushroom soup
1 lb ground beef (optional, I only add this once in awhile)
1/2 cup of sour cream
3/4 cup cottage cheese
flour tortillas (I prefer whole wheat)
2 cups shredded cheese (or just fist fulls like I use)
Break up the ground beef into small pieces, cook until brown. Mix the chili, cream of mushroom soup, sour cream, cottage cheese, and ground beef together with half of the shredded cheese. In a baking dish layer the tortillas and the chili mixture and sprinkle each layer with the remaining cheese...about 3 layers. Cover with aliuminum foil and bake at 350 for approx 35 mins.
You can prepare it to the point of putting the foil and and then put it into the freezer if you like, or you can cook it and then freeze it.
Go out to recipe.com and search for easy meals and casseroles, you'll get pleanty.
You can also go buy frozen lasagnas, chicken fettucini alfredo, and other items likewise at the store in the frozen section.
Remember spaghetti, salads, sandwiches are all easy and hubby can be helpful with those.
When/if you have a baby shower or blessing way, request your guests bring a recipe or a meal freezer-ready. It will help out a ton and people are usually willing to do that.
