Crudités, lol, we are not talking about a posh finger buffet. Peeling a few carrots and putting in clingfilm can be done the day before, and cutting some cucumber in 2 inch chunks and cutting in 4- takes, 3 seconds I suppose.
If parents cannot cut a piece of cucumber or peel a carrot or 2, what chance is there of them cooking a proper meal in the evening???
My mum worked in a responsible job, and had to commute. so she prepared our meal for lunch-time the day before, not sandwiches, a proper meal and dad and us kids re-heated it and added veg or salad (no microwave in the 50s) - as there was no school meals or supervised lunches- and it was the tradition to have main meal at lunch-time. Now that was hard, I must say. My kids had school lunches- and I am so grateful for that. Never ever made a packed lunch- a choice though.
