I have no actual pictures but your thread reminded me of this article I was discussing with OH last week :
https://www.netmums.com/children/toddler-portion-sizes
I cannot believe that some kids would be happy with such tiny portions, let alone that that is what they are 'meant' to have.
For example, Summer will eat half a cucumber or a whole carrot 'just' for a snack. Maci will easily eat half a packet of grapes or blueberries in a sitting.
And I could imagine their faces if I gave them 1/2 a chocolate digestive biscuit haha!
I'm not much help to what you asked for, sorry. But my kids eat a lot of often, mostly healthy and they love their fruits and veggies.
A typical lunch for my 4 year old would be a ham sandwich, 10 grapes, 2 handfuls of blueberries, a yogurt. Then she'd snack on raisins or crisps or something in the afternoon before dinner.
