I totally sympathize with your kid... I'm the same way, fruit and veggies don't fill me up
Yogurt with wheat germ
Cottage cheese with fruit
Fruit smoothie
Cereal
Crackers and cheese
Raw carrots with ranch dressing for dip
Whole wheat tortilla with fat free refried beans and cheese
My pediatrician has a poster with a lot of ideas on the office door but I can't remember anything, doh.
