Get your Kids Cooking !
I have found that one of the best ways to get your kids to be healthier eaters, is to let them shop and cook with you. Yes, it may be a little more effort, but letting them be involved in the choices and the preparation of meals, will definitely give them a vested interest in eating better. Start them off early with Good Nutrittion for a life time of healthy habits.
Here is a link to some yummy pocket snacks for the kids, from Eat Fresh.
