Preheat the oven to 350°F and grease a 12-cup mini cheesecake pan.
In a food processor, pulse graham crackers into crumbs, then mix with melted butter.
Divide the crust mixture into the cheesecake cavities, pressing it down firmly. Bake for 5 minutes, then reduce the oven temperature to 325°F.
Beat cream cheese and sugar until smooth. Add strawberry preserves, vanilla, salt, and an egg, mixing until smooth.
Fill each cavity with the cream cheese mixture and bake for 18 minutes, until set. Let cool and chill for at least 3 hours.
For the topping, heat cream and pour over chocolate chips. Stir until smooth, then let cool to thicken.
Top each cheesecake with ganache and a strawberry. Serve or store in the fridge for up to 1 day.
