Try a pasta bake using wholemeal pasta and very little of it with cheese, chicken and grated vegies. DS1 not good with vegies but this way he doesnt notice!!

Slow cooker meals can grate lots of vegies and can thicken sauce at end with corn flour (ds1 loves sausage casserole, lamb shanks, curried chicken)

scrambled eggs, omlette (hide vegies)

Birds eye make bubble and squeek pattie things

We currently are living on sandwiches and yougurt mainly with occasional other meal eaten!! GOOD LUCK
