For most of us, the diet starts January 1. Until then, you're inclined to celebrate, socialize, and eat with abandon. But the holidays don't have to be about overindulgence: You can have fun, eat healthfully, and still enjoy the usual party nibbles. The recipes on these pages offer good-for-you versions of four classic hors d'oeuvres. They have all the festiveness and flavors, but not quite as many calories. So instead of a scallop ensconced in bacon, try a mango-wrapped shrimp with an adobo sauce that mimics bacon's smokiness. Or a crunchy no-dough pot sticker, a creamy (mayonnaise-less) spinach dip, or gravlax served in a lightened-up way (you won't even miss the potato latke or bread).
