Place the bran flakes in a zip-top bag and crush them to fine crumbs with your hands. Place 1 tablespoon of crumbs in each of the ten shot glasses.
Beat the cheese and yogurt together in a medium bowl using an electric mixer. Whip until smooth.
In a separate bowl, stir together the sweetened condensed milk and lime juice. Add the lime mixture to the cheese mixture and beat until well combined. Divide the mixture evenly and tint one portion with the green food color, if using.
Place each portion of batter in a disposable piping bag with the tips snipped, or in zip-top bags with the corners snipped. Pipe the white batter into the glasses halfway up; tap each glass on the countertop to level the cheesecake. Repeat the process with the green batter.
Garnish the tops of the cheesecake shots with additional bran crumbs (you may have some crumbs left over) Garnish each glass with a lime wheel.
