i was told recently, make up meatballs and freeze them raw. (then cook for 50 mins on a tray, close together, at 180 degrees).

Homemade soup is a good one to freeze.

Homemade lasagne. I freeze it in dinner sizes. E.g the lasagne dish makes 12 squares of lasagne. we eat three squares per meal. so i gladwrap up four packages of three squares.

Freeze things thin, for quicker defrosting. e.g chicken schnitzels.

Homemade sausage rolls.

i'm a pretty basic cook, i'm sure much more experienced cooks will come along and give you many more ideas.

THis is not about FREEZING or PRE-COOKING, but something i wish i had done, before i had my bub, was
- automate bill paying (online)

- set up online supermarket shopping (at least for the basics)

- set up online fruit n veg shopping (so there's always "grab n go" healthy food in the house, when you're too tired to cook/make a sandwich) - the most important bit in these last two, is the delivery part.

- having lists on the fridge, so if you don't set up auto shopping, then when people visit and say "what can i do to help" - and you are frazzled, just give them one of your lists on the fridge "could you go and pick this shopping up please"? and then you've made them feel useful, and you've gotten something you actually need, done.

- booking a cleaner for once a fortnight (for e.g) to do the wet areas for first six weeks.

i lived off weetbix for the "early daze", all the plans of dh doing grocery and fruit/veg shopping didn't work out, too much else happened. At the time, we were both too exhausted to work out online shopping, so it just didn't get done. Just to have had fresh fruit around, to be able to grab and munch, would have made such a difference.
