2 c. summer fruit (pineapple, oranges, and strawberries work great)
1 tsp. sugar (optional)
1 tsp. lemon juice

Puree fruit in blender, adding a teaspoon or two of water if necessary. Add sugar (if desired), a lemon juice and blend. Pour into bar molds or small cups and insert sticks. Freeze until solid. For most fruit it'll be less than 50 calories a serving. Makes 4 (4 ounce) bars.
