Preheat your oven to 325°F (160°C).
In a mixing bowl, combine the graham cracker crumbs and melted butter. Press this mixture into the bottom of your springform pan and bake for about 10 minutes. Let it cool.
In a large mixing bowl, beat the low-fat cream cheese until smooth. Add the Greek yogurt, egg, sugar, vanilla extract, and salt. Beat until creamy.
Pour the cheesecake filling over the cooled crust and smooth the top.
Bake for about 30-35 minutes, or until the edges are set. Allow to cool in the oven with the door cracked for an hour.
Refrigerate for at least 4 hours, or overnight.
Carefully remove the sides of the springform pan and top with fresh mixed berries before serving.
