I will sneak extra vegetables into the kids meals, but I am also a big believer in introducing the kids to different things. How do the children know that a carrot tasts good if they think they have never eaten one (refering to hiding all veggies in food). I usually serve two different veg choices at lunch and they must eat at least one. They always do sometimes i say " You can be done when you eat your....." or "would you like to eat ........... or .................?"
