It's amazing, isn't it, that so many of us are conscious when it comes to UPFs and healthy food, but when it gets to something as simple as school lunches, it all goes out of the window in the name of time and effort.
There are many amazing options you can go for that don't take hours to make.
Mine have sushi, pasta salad, sandwiches, wraps or crackers for carbs. Mixed salad, vegetable sticks and fruit to keep them full. Some form of pudding - biscuits, chocolates, cakes.
Sushi and pasta salad or mixed salad are made in half an hour and most of that cooking time, I can ignore the food on the hob and get on with other things. It takes less than 5min to chop the vegetables, roll and chop the sushi or mix the other ingredients. Hell, you can even make a healthier version of lunchables in less than 5min. The fillings for sandwiches are easily made. Most things can be done the day before if you get stressed in the mornings. To claim you don't have time to make a packed lunch is a poor excuse.
It gets eaten - not always all of it (school lunch breaks are far too short if they also want to run around), but certainly enough to keep them going until dinner time. Many school dinners are awful, both in quality and quantity.
And I will end this post with the usual disclaimer that yes, I am aware of AFRID and neurodiversity, but as always, this post is still about the vast majority of kids who are neither.
