Frozen and then defrosted sandwiches can go a bit "soggy" OP. Just a warning.
I find packing a school lunch in the morning whilst DS munches on shreddies no bother.
I'm not one of those parents though that puts much "variation" in there and nothing is like home made with love 😳
I tend to put a selection of the below in
Ham sandwich or cheese sandwich (always)
Crisps
A fromage frais and spoon. (Always)
Some carrots Barton's or cucumber sticks
A babybel
A club or penguin bar
A piece of fruit (always)
Colder months the flask comes out, and in lieu of sandwiches I pop in the odd hot food like;
Sausage and beans in a tin with bread and butter
Tomato soup (from a tin) with a buttered bread roll.
Left over pasta bake.
With them some snack things like the yoghurt, babybell and always a piece of fruit.
I'm lucky DS in a state school and there are no lunchbox police, they are happy to just see food in the lunch boxes. Kid lives of 90's packed lunches, did me no harm 🤣
