Prep the Bananas: Peel and slice the bananas in half lengthwise.
Arrange them in two serving bowls and sprinkle evenly with cinnamon.
Create the Slurry: In a small bowl, whisk the cornstarch and pineapple juice together until completely smooth.
Set aside.
Warm the Sauce: Combine the Greek yogurt, crushed pineapple, and honey in a small saucepan.
Whisk gently over medium-low heat until just warmed through.
Thicken and Finish: Increase the heat to medium-high.
Pour in the cornstarch slurry and whisk constantly for 1-2 minutes, until the sauce thickens.
Assemble and Enjoy: Immediately spoon the warm pineapple sauce over the cinnamon-dusted bananas.
Garnish with an extra dash of cinnamon, if you like, and serve warm.
Add texture and flavor with toppings like toasted walnuts, shredded coconut, or fresh berries.
