In some cases, the key to calorie restraint is about portions. Serving bite-size morsels that come in their own portion-controlled package, like Bruschetta with Peach Salsa and Melted Brie, adds a natural layer of restraint (as long as you can keep from eating the entire batch). And in other recipes it's all about smart ingredient choices. We substitute lower-fat ingredients when it makes sense (and when it tastes good), and we always try to serve appetizers with fresh veggies or fruit to round out the nutrition (and it also makes for a pretty presentation). At under 100 calories, each of these appetizers are sure to inspire your next gathering.
