Arrange a meal train if you haven't already. There's a website (mealtrain.com) if you want something a bit more organized. But even just an email to a whole bunch of people will do it. Ask who can bring food and on which day (obviously ask which day after baby arrives). Not everyone will do it, so ask everyone you can think of, you may get help from some unexpected sources.
If you have the freezer space, prepare and freeze stuff beforehand. Ask friends/family to prepare/freeze stuff for you beforehand. The easiest way is to just start doubling recipes. One for dinner, one for the freezer. Freeze things that just need minimal prep afterwards (heat/cook and serve). If there are any "convenience foods" that you are comfortable with, stock those, either in the freezer or the pantry. You don't need to do a big "stocking up" for this - you can set aside $5-10/week of your budget and add one or two items to your shopping list each time.
Right now, my freezer has in it:
Raw meatloaves in throw-away mini loaf pans (I get 3 pans to 2 lbs of meat). This can go from freezer to table in 90 minutes with no other prep. Toss a potato into the oven next to it and you have a meal. My meatloaf is full of veggies so it doesn't need anything else.
Fresh pasta (ravioli/tortellini)
Lots of stock (side effect of cleaning out bones, but frozen in 2-3 c portions for ease of use to make quick soups).
Some random convenience foods - there might be a bag of potstickers or something similar buried in there, which is a really quick meal. A bag of sweet potato "tater tots" or fries for an easy side.
Sweet potato pie filling (we use this to make SP pancakes)
Homemade sauces frozen in small amounts (pesto, mole, etc.)
I may also be adding:
cooked beans (for refried, hummus, baked beans, soups, whatever)
a few casseroles
Pantry always has:
Dry pasta (incl Mac & cheese)
Oats and other grains to make oatmeal/porridge
A few random sauces/salsas to finish off a meal (enchilada sauce, pasta sauce, etc.)
Random veggies - pickles, marinated artichokes, olives, green chiles, etc.
In addition to all that, I'll be making up jars of both mixed grain oatmeal for the crockpot (dump, add water, turn on, walk away), and probably muffin mix (flour, sugar, leavening, CO - add milk and eggs) for quick and easy breakfasts. I keep GF pancake mix on hand, and I may get frozen waffles, although I'm the only one that eats them.
I'll be sure that the pantry also has onions, garlic, potatoes and sweet potatoes on hand. That allows me to just toss a spud into the oven to bake next to a meal, or make up a quick (5 minute) pasta sauce if necessary.
For fresh food, I'm joining a CSA again this year - they deliver to my door, and I'm going to get a "ready to eat" box, so nothing that has to be cooked. I pick up milk weekly from our cow share, and I can get eggs from him too if I don't want to go to the farmer's market for them. Bread and the like I can either walk down to WF (2 blocks), or I can ask DH to pick it up on his way home from the train. Meat will depend on the state of my freezer - I used to belong to a monthly meat CSA, then stopped when I got pg so I could work on cleaning out the freezer(s) - I may rejoin or I may just start buying for a couple weeks at a time. Mostly large roasts and ground beef, since they require the least amount of prep work.
I also asked people to bring a dish for the freezer to my mother's blessing. I didn't really get into all of our food rules because most people wouldn't know what to do with them. But I did stipulate no soy, no oranges and no grapefruit (DS' allergies), and I'll be thankful for whatever we get.
Personally I do get hotdogs and have them in the house periodically. I get the nitrate-free ones from our local/pastured/organic herd, and I'm okay with that. DS loves them. However, I wouldn't be depending on only them for my pp meals, they're mostly a quick and easy meal for the toddler. Chicken nuggets though are beyond my comfort zone. I haven't seen any that I'm comfortable with the ingredient list, nor have I tried any that taste anywhere near as good as my homemade. I have a big jar of the breading for them in the pantry, so if DH wants chicken he can make it easily enough (eggwash, breading, pan). He's proven over the years that he can follow a recipe, so long as I don't ask him to get creative.
