In a blender, combine the frozen mixed berries, water, sweetener, and lemon juice.
Blend until the mixture is smooth and creamy.
Pour the mixture into a freezer-safe container and freeze for at least 2 hours or until the sorbet is firm.
When ready to serve, remove the sorbet from the freezer and let it sit at room temperature for 5-10 minutes to soften.
Scoop the sorbet into bowls or glasses and enjoy!
