My 14 y/o loves the little grape tomatoes after school.....in fact once she ate an entire Costco container of them! Yikes!!!
I'm lucky that both my girls love veggie snacks -- what they love the best is multi colored bell peppers (red, orange, green) with hummus or cottage cheese to dip the into, and the afore-mentioned baby tomatoes. They also love carrots cut on a slant like chips, and dipped into salsa. Don't knock it til you try it!
