01 - Line a baking sheet with parchment paper or arrange silicone mini muffin molds on a flat surface for easy filling and freezing.
02 - Combine the Greek yogurt, honey, and vanilla extract in a medium bowl. Whisk thoroughly until the mixture is completely smooth and evenly sweetened.
03 - Gently fold the diced strawberries, blueberries, and mango into the yogurt mixture using a spatula, taking care not to crush the fruit pieces.
04 - Drop heaping tablespoons of the yogurt-fruit mixture onto the prepared baking sheet, leaving space between each bite to prevent sticking during freezing.
05 - Sprinkle each bite generously with mini dark chocolate chips or chopped nuts if desired, pressing them lightly into the surface to adhere.
06 - Transfer the baking sheet to the freezer and chill for at least 2 hours or until the bites are completely firm and set throughout.
07 - Once fully frozen, remove the bites from the baking sheet and transfer to an airtight container. Keep stored in the freezer until ready to serve.
