Mix the strained yogurt with honey and vanilla until smooth.

Spread the yogurt mixture evenly about 1 centimeter thick onto a parchment-lined tray.

Sprinkle sliced strawberries, blueberries, and crushed almonds on top.

Place the tray flat in the freezer and freeze for at least 3 hours until fully set.

Peel the frozen layer off the parchment paper and break it into irregular pieces by hand or with a knife, then serve immediately.
