01 - Line a baking sheet with parchment paper or arrange silicone mini muffin molds on a flat surface.
02 - Whisk together the Greek yogurt, honey, and vanilla extract in a medium bowl until completely smooth and well combined.
03 - Gently fold the diced strawberries, blueberries, and mango into the yogurt mixture, being careful not to crush the fruit.
04 - Drop heaping tablespoons of the fruit-yogurt mixture onto the prepared baking sheet, leaving space between each portion to prevent sticking.
05 - Sprinkle mini dark chocolate chips or chopped nuts over each bite as desired, pressing lightly to adhere.
06 - Transfer the tray to the freezer and chill for at least 2 hours or until the bites are completely solid throughout.
07 - Once fully frozen, remove the bites from the tray and transfer to an airtight container. Keep stored in the freezer until ready to serve.
