Zest the limes first, then juice them; it's easier that way. Mince the lime zest and set aside for a moment. Place the lime juice, silken tofu, and cream cheese in a food processer, and process until completely creamy and smooth.

Pour mixture into the graham cracker pie crust, and chill in the refrigerator for 2-3 hours.
