I saw the wisdom in what my mum used to do:
Roast on Sunday. She alternated beef, pork, chicken and ham and then at some point threw meatloaf into the mix too.
Leftovers on Monday.
Sandwiches and / or soup made from juices from roast or ham bone or Erin soup packet on Tuesday.
Spaghetti bolognese or curried beef on Wednesday (alternating weeks).
Macaroni and cheese on Thursday using leftover spaghetti
or on a curry week, curried rice with veggies and hardboiled eggs and any leftover curry.
Fish on Friday even though she hated fish and the sight and smell of them made her sick. Sometimes fish fingers were served.
Saturday was often rashers, eggs, sausages, plus scones or pancakes for dinner, or sometimes a stew. In summer, a salad with soup and bread, sometimes potato salad.
She managed to crank out a homemade dessert most days and we had lots of veggies with all meals. Dad wanted potatoes with everything
.
Although I'm not as organised as she was and I am also a more 'international' cook, I try to make one large meal and then serve leftovers the next day, aiming to cook only about three times a week. I also cook in large batches, especially items like tomato based sauces that I use for all sorts of things. If I make a stew or soup I make double or more and freeze. (All in portions I know I will use in one meal, nothing larger).
I try to use the slow cooker, and get chopping, skinning, etc., done early in the day. I also have a bread machine and use the delay timer to have pizza dough ready to go for soon after returning home or bread fresh when we get up. If you put your dinner ingredients in the slow cooker and leave it in the fridge at night remember to take it out in the morning and turn on the slow cooker before you leave
Best tip I have is make a meal plan at the very least once a week so you are not faced with the drudgery and pressure of answering the 'what's for dinner' question every single morning of your life.
And next best one is do as much as you can in the morning because you don't know what the afternoon will bring or how frazzled you will be by then.
Third tip is get your DH to do stuff like ironing if you iron or take care of something like bathroom deep cleaning once a week. Or if he is home then he can do some cooking.
And TV is your best friend. Do not listen to anyone who says anything else.
When DD3 was small she was very screechy and clingy and annoying to everyone else she used to turn the TV off constantly so I would put her in her back carrier and cook with her strapped onto my back.
Cluster feeding is a hard time to get through but it does pass.
