Glad you enjoyed camping!
Have a look round the MN Camping Board for threads about ‘lovely set up’, food and kit.
I have a ‘high performance’ passive cool box. I.e not electric but very good insulation. Examples are the Coleman Xtreme, or pricier ones from Icey Tek or Yeti. But they last forever. If you pre-chill and fill with frozen / chilled food and good blocks or ice they are good for about 4 days.
You can take a pre/frozen curry or bolognrse sauce, for example, something (frozen) to BBQ, and keep milk cold.
Pouch food is also good. Microwave rice can be heated quickly in a pan. Or a pouch of re-fried beans, packs of tortilla keep well, can of chilli, microwave ‘Mexican rice’.
Pack of tortillas, 2 sandwiched together with ready grated cheese, refried beans or tinned corn or anything you like, dry fry in frying pan : Quesadillas!
Basically you want things that are quick to cook, not long simmering stuff that wil use up all your gas.
Bags of brioche rolls, the individually wrapped pains chocolat, bananas, satsumas.
I have never eaten a pot noodle when camping. And as a family we used to cook over the campfire and do whole chickens with veg and spuds in a Dutch Pot, but now I camp in smaller groups / everyone is veggie / the novelty of campfire cooking as an activity in itself has worn off I mostly can’t be arsed.
You get used to your camping style, what suits you, what you need, what is unnecessary ‘stuff’.
