Preheat the oven to 325℉. Spray an 11x5-inch (or 9x5) loaf pan with non-stick spray before lining with a piece of parchment paper the same width as the pan with the paper edges left to hang over the sides of the pan.
In a large bowl whisk together the olive oil, brown sugar, white sugar, eggs, and vanilla until fully combined. Add the mashed bananas and sourdough discard and whisk until combined. Add the salt, flour, and baking soda and stir just until incorporated. Do not overmix! Stir in the chocolate chips.
Pour the batter into the prepared loaf pan and bake for 55-70 minutes or until a toothpick inserted into the center comes out clean. (You may need to bake 5-10 more minutes if using a 9x5-inch pan.) Let cool in the pan for 10 minutes before lifting out of the pan using the overhanging parchment paper to lift. Let cool completely on a wire rack. Enjoy!
