Some of the things mentioned in the new guidelines are a bit of a red herring at least for many primary schools who are already doing a lot of what is being suggested, it’s at secondary level where the big overhaul will have to happen. Most if not all schools got rid of their deep fat fryers 20 years ago. I have never seen fried eggs served in any school, all day breakfast is a popular menu option, but for the eggs scrambled or omelette style is usually the go to option as they’re easier to prepare and serve on a mass scale. Bacon and sausages are oven baked.
I think there needs to be a balance struck, I am all for providing healthy meals and different food experiences at school but if children don’t eat it and it ends up in the bin then it’s no use to anyone. I think there are ways of adapting things that children are typically familiar with to improve nutritional content without them necessarily realising it. Blending veg into sauces (already happens in a lot of schools), whole grain pizza bases, hand cut oven baked skin on chips or wedges, beef burgers where beef mince is mixed with broccoli to make the patties, serve with 50/50 or whole meal buns and salad and I don’t see the issue with that as a meal at all. It’s familiar, but still decent nutritionally, the average school child is likely to want to eat it.
A mix of things like the above and some different options would be the way to go. If kids like and enjoy the healthier version of things they already eat at school, that improves their overall impression of school food in general and they may be more likely to try other things on the menu.
I’m not sure on things like banning adding salt, if It means not adding it to sauces etc, a little is ok even for children and can go a long way in improving the flavour of a dish so they enjoy it. Chips at most school whilst frozen, have just potatoes and usually sunflower oil listed as the only ingredients and are oven baked, so no worse than roast potatoes really, which use the same ingredients and cooking method.
But in answer to op’s question, no I don’t think it’s a step too far since fried eggs aren’t common place in school kitchens in the first place.
