Depends on what you define as junk.
Crisps, chocs, fizzy drinks? Including hotdogs, burgers, French fries etc?
We don't like hotdogs or burgers unless the veggie variety. Nothing fried in the frying pan unless it's pancakes or omelettes.
Packed lunch - a sandwich or wrap, salad in pita.
Grapes, strawberries, blueberries etc and/or dried fruit.
No crisps or chocolates in lunchboxes here (school rules guidelines)
Breakfast - cornflakes or wheetabix, toast with Nutella.
Main meals - shepards pie & spag bol (quorn), veggie curry and Mac cheese from scratch all with side vegetables.
Fish fingers/pork sausages with mash, jackets, oven chips.
Nothing wrong with beans on toast either (my DP thinks this isn't a meal) or homemade soup with fresh crispy bread.
Pizza occasionally.
Fruit
Biscuits (daily, small snack packs in lunchbox)
Cake would be a treat, not daily but I bake once a week if I have the time.
Takeaways - fish & chips from the local or a subway 6incher lunch maybe once or twice a month
DD isn't crazy about candy sweets but would eat ice cream daily if left to her own devices
An ice pop after school on warm days.
Water with and without cordials.
Hot chocolate in Autumn/winter.
No fizzy drinks though now she's older she will have a lime cordial and soda water if I have.
DD is 10. I say a little of what you fancy doesn't hurt.
