Start by freezing the sliced bananas and strawberries. Spread the banana slices and frozen strawberries on a parchment-lined baking sheet in a single layer. Freeze for about 2-3 hours or until completely frozen

Once the fruit is frozen, you can proceed to make the sorbet

In a blender or food processor, combine the frozen strawberries and frozen banana slices

Add the lemon juice, granulated sugar, and vanilla extract to the blender

Blend the mixture on high until the ingredients are well combined and the mixture becomes smooth and creamy. You might need to stop and scrape down the sides of the blender to ensure even blending

Taste the mixture and adjust the sweetness by adding more sugar if needed, depending on your preference and the natural sweetness of the fruit

Once the mixture is smooth and well-blended, transfer it into an airtight container

Place the container in the freezer for an additional 2-3 hours, or until the sorbet firms up

When you're ready to serve, let the sorbet sit at room temperature for a few minutes to soften slightly for easier scooping

Scoop the Frozen Strawberry Banana Sorbet into bowls or cones and enjoy the delightful combination of flavors
