Lighten Summer Fare with a Fish Dish

It can be hard to eat light during the summer. The grilling, the potato salads, the ice cream sundaes are everywhere. But you can cut some calories this summer -- with fish!

Shaun Hergatt, executive chef of and partner of the restaurant Sho in New York, demonstrated how to whip up a no-bake fish classic: ceviche, on "The Early Show" Friday.

Fish is a great choice for summer, according to Hergatt. Summer is a season when most fish are easy to find, he says, and when fish are often at their most delicious. Also, he says, it's a good, light way to eat if you're worried about calories, and there are endless ways it can be prepared.
