“Kids do get tired of the same old sandwiches,” says the visiting professor of exercise science at Willamette University in Salem, OR. She’s also the author of numerous books, including Age-Proof Your Body: Your Complete Guide to Looking and Feeling Younger.

A tortilla wrap is a great way to experiment with a variety of healthy ingredients, Somer says, and tortillas are a good choice for budget-conscious families.
