Prepare the Ingredients. Preheat your oven to 350°F. Grease a 9x5-inch loaf pan. Mash the bananas in a large mixing bowl. Dice the strawberries and set aside.
Combine the Wet Ingredients. In the bowl with the mashed bananas, add melted butter, sugar, beaten egg, and vanilla extract. Mix until well combined.
Mix the Dry Ingredients. In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add the dry ingredients to the wet ingredients, stirring just until combined. Gently fold in the diced strawberries.
Bake the Bread. Pour the batter into the prepared loaf pan. Bake for 50-60 minutes or until a toothpick inserted into the center comes out clean. Let the bread cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
Serve. Slice the bread and serve as is, or spread with butter or cream cheese for extra indulgence.
