- Cocktail Tomatoes
In a blender, process watermelon, tomatoes, water, agave, lime juice, and salt until smooth, about 1 minute.
Pour into a shallow freezer-safe container and freeze for one hour.
Using a fork, rake the mixture well and freeze again. Repeat this process two more times or until granita is frozen to a desired consistency.
Serve in a glass garnished with lime zest.
