Preheat your oven to 350 degrees and line a muffin tin with paper liners. In a large bowl, mash the bananas until smooth. Add the olive oil, honey, Greek yogurt, eggs, and vanilla extract, stirring until everything is fully combined. Add in the flours, baking soda, and salt, mixing just until the batter comes together, being careful not to overmix. Fold in the chocolate chips. Spoon the batter into the muffin cups, filling each about three quarters full. Bake for 18 to 22 minutes, depending on size, until the tops are golden and a toothpick inserted in the center comes out clean. Let cool slightly before serving.
