The note adds that the sausage rolls 'do not fit with our service's nutrition guidelines. For some healthier lunchbox ideas, ask an educator, or go to the Good for Kids website.'
The infuriated mother took to the Mums Who Cook & Bake Facebook page to vent her frustration, leading many mums to slam the school as ‘rude’.
The mum wrote: 'So I cooked my butt off... included in the cook were sausage rolls loaded with veg I sent them off to preschool with them to return along with this note.’
She added: 'My son takes the same sort of lunch every day fruit fruit and more fruit veggies and meat and cheese. In my opinion these sausage rolls are pretty healthy for him I will be sending the information back to the school.
'They do not allow the food item to be eaten once they attach the note I had a feeling this would happen so I packed extra for him. I also packed two Milo balls just to see if they also said no to them, guess what they were allowed.'
The post was met with disbelief from fellow mums.
Wrote one: 'Preschool teachers are not nutritionists. I'd be furious. How dare they.'
It’s the latest in a long line of lunchbox scandals, where mums have been slammed by teachers acting as ‘lunchbox police’.
Earlier this year, a mum was slammed by her daughter’s teacher for packing too much in her lunchbox - while another was banned from baking cookies for her son... unless there was enough to feed the whole class.
‘The world’s gone mad!’ wrote one disbelieving mum.
