Preheat the oven to 350 degrees F. Grease a muffin tin.
In a large bowl, combine the mashed banana, pumpkin puree, Greek yogurt, olive oil, honey, eggs, vanilla, and pumpkin pie spice. Stir until well combined.
Add the flour, baking soda, and salt to the bowl. Stir until combined, then fold in the chocolate chips.
Portion the muffin batter into the muffin tin. Bake at 350 degrees F for 17-20 minutes, or until a toothpick pulls out clean from the center of the muffins. Enjoy!
Notes
Be sure to use a banana with ample brown spots or large browning areas, as this will be softest and sweetest for making these muffins.
