Preheat the oven to 170C. Grease a standard loaf pan and set aside.
In a medium bowl, combine the flours, baking soda, and sea salt. Set aside.
In the bowl of a stand mixer fitted with the paddle attachment, beat the butter on low until it’s pale and light, about 3 minutes. Add the sugar and continue to beat until fully combined. Scrape down the sides, and then mix in the eggs one at a time. Next add in the bananas, yogurt, and vanilla. Fold in the flour, and then strawberries, mixing just until combined. If you’d like, reserve a few berries for the top of the bread.
Pour into the prepared pan and bake for 60 – 70 minutes, or until a toothpick inserted in the middle comes out with just a few crumbs attached. My bread browned considerably in the oven check bread towards the end and tent edges with foil if needed.
Cool for 20 minutes, remove from bread pan, and cool 40 minutes more before serving.
