Peel the bananas and cut each in half crosswise to create four pieces.
Insert a wooden popsicle stick into the cut end of each banana half, pushing it about halfway through.
Line a small baking sheet with parchment paper or a silicone mat.
In a shallow bowl, whisk the Greek yogurt and honey until well combined.
Dip each banana half into the yogurt mixture, using a spoon to coat all sides evenly.
Roll the yogurt-coated banana in the granola or crushed nuts, pressing lightly to adhere.
Place the prepared bananas on the baking sheet ensuring they do not touch.
Freeze for at least 4 hours or until the yogurt is frozen solid.
