A fun way to use up any remaining watermelon
8 c. cubed seedless watermelon
1/4 c. sugar
1/4 c. lime juice
2 c. diet 7-up (or regular)
In a blender or food processor, cover and process the watermelon, lime juice and sugar in batches until smooth. Pour into a freezer proof container. Cover and freeze for 30 minutes or until edges begin to freeze. Stir and return to freezer. Repeat every 20 minutes or until slushy. About 90 minutes. Spoon 3/4 c. into glasses and add 1/4 c. soda. Yields 8 servings.
