An Egg-ceptional Summer Snack

Its summer, and you and your kids are on the go. Vacations, soccer games, concerts, play dates you name it. And if you’re looking for simple, compact, healthy snacks to keep everyone full and fueled, look no further than the egg carton in your fridge. One medium-sized hard-boiled egg contains 6 grams of protein and significant amounts of B vitamins, vitamin A, vitamin E, iron, zinc, iodine and selenium. Thats a pretty complete and natural nutritional punch for only about 70 calories. Just make sure to keep eggs chilled to avoid food-borne illness.
