From experience of 2 DS having gone through this, bear in mind that storage is really limited.
We prioritised cutlery & crockery for 2, so in theory there would always be a clean plate or bowl available.
2 pans pref with lids one for pasta/rice and and the other for a sauce, lid also means food can be drained more easily if the colander has disappeared.
Small frying pan for meat and veg eg bolognese.
A small baking tray for oven chips/ fish fingers and a small baking dish - the enamel ones work well as they’re light, virtually break proof and can be used with foil in place of a lid.
Some cheap spatulas.
Items like colanders, tin and bottle openers tend to be used communally so take cheap ones and expect them to disappear! Same with tea towels.
We took a couple of collapsible crates with dry goods like pasta, rice, sauce, orange juice (for the vitamins) and DS stored them under his bed to use as needed.
It meant he had a ready supply to get him through the first couple of weeks while finding his way round but the items were safely stored so didn’t disappear.
Vodka, coke, (substitute drinks of choice) and a cake or box of sweets all to share is great for breaking the ice after parents have left.
Plus a wedge to hold the bedroom door open when you’re working but still want to
be sociable.
