Figs
Fiber-rich figs are low in calories at 37 per medium (2.25" diameter) raw fig and 48 per dried fig. A recent study by the USDA demonstrated that they contribute to a feeling of fullness and prevent overeating. Subjects actually complained of being asked to eat too much food when fed a diet containing more figs than a similar diet with an identical number of calories.
Serve them with other fruits and cheeses. Or poach them in fruit juice and serve them warm or cold. You can stuff them with mild white cheese or puree them to use as a filling for cookies and low-calorie pastries.
