In a high-powered blender, combine all ingredients: frozen strawberries, lime juice, agave nectar or maple syrup, water, and salt.
Blend until smooth and creamy, scraping down the sides as needed. The mixture may be slightly thick at this point.
Taste and adjust sweetness or tartness as desired. You can add more agave nectar or maple syrup for sweetness, or more lime juice for tartness.
Pour the mixture into an ice cream maker and churn according to manufacturer's instructions. This will take about 20-25 minutes.
If you don't have an ice cream maker, you can still make sorbet! Pour the mixture into a shallow baking dish and freeze for 2-3 hours, stirring every 30 minutes to break up the ice crystals. This will result in a slightly icier texture, but still delicious!
Once frozen, scoop the sorbet into bowls and enjoy! Top with fresh mint leaves, vegan whipped cream, or lime zest for an extra special treat.
