01 - Line a baking sheet with parchment paper or arrange silicone mini muffin molds on a flat surface.
02 - Combine Greek yogurt, honey (or maple syrup), and vanilla extract in a medium bowl. Whisk until completely smooth and evenly incorporated.
03 - Gently fold the diced strawberries, blueberries, and mango into the yogurt mixture using a spatula. Be careful not to crush the fruit.
04 - Drop heaping tablespoons of the mixture onto the prepared baking sheet, leaving space between each portion. Alternatively, spoon the mixture into mini muffin mold cavities.
05 - Sprinkle mini dark chocolate chips or chopped nuts over each bite, if desired. Press gently to ensure toppings adhere.
06 - Transfer the tray to the freezer and chill for at least 2 hours, or until the bites are completely solid throughout.
07 - Remove frozen bites from the tray and transfer to an airtight container. Keep stored in the freezer until ready to serve.
