Well, we have a family of 6, and I come from a family of 11 kids (yes some of those are adopted) and our family knows how to EAT. 

For 1 I have to say I love my crockpot/slow cooker. Beef stew, roast, chilli , soup are all easy to just throw in a big crockpot and let cook.

Other meals I make in bulk are pasta, meatloaf ( I make mini meatloafs, easy to freeze and the little ones love em cause they are "kid size"), lasagna, stuffed shells (these you can sneak healthy spinach in without the kids knowing) Manacotti, homemade burgers and frys are cheap and easy, I usually serve it with coleslaw, and of course the normal meat and potatoes meals with beef pork or chicken,sausages and perogies, tacos, casaroles, baked macaroni and cheese and once every 2 weeks we have pizza night to give mom a much needed break from the kitchen lol.

Children at that age are SUPER hungry! so I can only imagine how much food you must go through. There was only 3 of us kids in our family growing up, but man!! did we eat at that age.

I also have 6 children but mine are younger, so wouldn't eat as much as yours. I've found that having lots of freezer space, and 2 fridges helps. I do my shopping fortnightly and I just make sure when i shop I buy a huge variety of fruit, veg, meat ect so that during the day when I'm thinking about dinner, i can just go to the fridge and always have fresh produce to make salads, veggies with whatever i make. I don't believe in the planning meals ahead, cause you never know what your going to feel like ect. So basically i do roasts, cold meat and salad with baked potatoes and all the other usual stuff like chops, mash and veggies. I think it's a good idea to always keep your meals simple and a bit of what everyone likes and just try not serve the same thing all the time, just change it a bit. 1 day have fried eggs with whatever your having then another day mash then another day baked and so on. Then when everyone has had enough of potato start cooking up rice and having fried rice with your meat and salad or veggies or whatever. Change what meat they are eating so they don't get sick of it. Hope that helps a little

I don't have a large family, but I would suggest if you haven't already, to start some batch cooking (also known as freezer cooking, or for the really keen amongst us once a month cooking).  Instead of making up a lot of small meals each night, one night cook a REALLY BIG batch of one meal and what doesn't get eaten goes into the freezer - in your case you may want to do it in individual servings, but it can also be done in a big meal serving too.  Then, the next night, make up a REALLY BIG batch of another meal and do the same with what's left over.  After a while your freezer will be stocked with heaps of leftovers, so you can just reheat instead of always cooking from scratch.  Like I said, I don't have a large family, but for those nights when I am exhausted and don't feel like cooking, but can't afford take away, I use up my freezer meals.  It's how I stay on top of sticking to a home-made meal plan.

As to what recipe suggestions I have - chicken/beef/pork curry.  You can buy the curry paste and all you have to do is fry the paste and onion, brown your meat, add the coconut milk and veges and leave it to cook, stirring occasionally.  I was always too nervous to cook a curry from scratch, but my husband's mum was born in Singapore and after a while he started to miss currys so he asked me to try and when I did try, I couldn't believe how easy it was, or how tasty it actually turned out to be.

I love pasta bakes.  They can be vegetarian or you can use chicken or tuna or whatever you like, for a really cheap bake I use sausages cut up into coins.

We also love quiche, and if you don't have a recipe, or find the ones you do have too fiddely, I have a great one that requires no crust, it's just mix together and bake.  Minti mail me if you're interested in it.

Sometimes if I start to think the meal I'm cooking is too boring, I will make a risotto to go with it.  Since I don't want it to be anything fancy or time consuming, I just add a chicken cup-of-soup, cream, crushed garlic and a couple of chopped veges to some cooked. rice.  It makes the meal more interesting, and goes with things like fish and chicken. 

I hope some of this helps.

Hi, I am the eldest of 6 kids, and Mum used to cook big pots of dinner! Lentil stew, beef goulash etc etc... She has a big pressure cooker... Even spag bog she used to do large amounts, and there were always leftovers, and trust me, we knew how to eat!!! ... Mum always made flatbread to go with the stews... My parents used to buy in bulk at markets also, and at the local fruit/veg barn Dad used to always bargain to get fruit that was near its useby date really cheap (much to us kids horror!) but I guess they had to as they only had the one income and 8 people to feed! The fruit was never off though, and if there was too much for us to eat before it went off, Mum made jam or pickles or dried the fruit.... We also grew our own vegies and had chooks for eggs (and also to eat!)..... Maybe look on the net? There might be a website that could give you more ideas?
