Prepare a 9-inch tart pan by spraying with nonstick spray and lining with parchment paper.
Soak dates in warm water for 10 minutes, drain, and halve.
Blend dates, cashews, and almonds in a food processor until a sticky dough forms.
Press the mixture evenly into the pan and slightly up the sides to form the crust.
Spread Greek yogurt over the crust evenly.
Arrange fresh fruit on top as desired.
(Optional) Brush fruit with apricot glaze for shine.
Chill or serve immediately. This No Bake Greek Yogurt Fruit Tart is best enjoyed fresh.
