Preheat the oven to 350°F. Lightly grease a 12-cup mini cheesecake pan with nonstick spray.

Place the graham crackers in the bowl of a food processor and pulse until finely ground. Add in the melted butter and pulse until moistened. Divide the mixture among the cavities of the cheesecake pan, about 1 heaping tablespoon in each. Firmly press the crumbs into the bottom of each cavity.

Bake the crusts for 5 minutes, or until fragrant. Remove from oven and reduce temperature to 325°F.

In a large bowl, use an electric mixer to beat the cream cheese and sugar on medium-high speed until smooth and fluffy. Add the strawberry preserves, food coloring (if using), vanilla, and salt and beat until smooth. Add the egg and beat until just combined. Divide the mixture among each cavity.

Bake for about 18 minutes, or until set. Let cool to room temperature. Cover with plastic wrap and let chill for at least 3 hours or overnight.

Place the chocolate chips in a medium heatproof bowl. In a small saucepan heat the cream just until simmering. Pour over the chocolate chips. Let sit for 3 minutes before stirring until the mixture is melted and smooth. Allow to cool and thicken.

Top each cheesecake with the ganache, then press a strawberry into the ganache. Serve or cover and store in the fridge for up to 1 day.
