They definitely prefer mixed food so I cater for that. Basically if they can see veggies they refuse to eat it.
I made a delicious chicken lasagne tonight with heaps of hidden veggies in there (broccoli, cauli, peas, corn, mushrooms, tomatoes) and DS2 ate most of his but it was with A LOT of encouraging and spoon feeding.
I admit I cave every now and then and just buy them dinner but I have cut out that completely in the last few weeks to really get on top of this issue.
Thanks so much for all your suggestions too
