Preheat the oven to 350°F (175°C) and grease a loaf pan.

In a mixing bowl, mash the ripe bananas until smooth.

Add sugar, melted butter, beaten egg, and vanilla extract to the mashed bananas and mix well.

In a separate bowl, whisk together the flour, baking soda, and salt.

Gradually add the dry ingredients to the wet mixture, stirring until just combined.

Gently fold in the chopped strawberries.

Pour the batter into the prepared loaf pan and smooth the top.

Bake in the preheated oven for 55-60 minutes, or until a toothpick inserted in the center comes out clean.

Let the bread cool in the pan for 10 minutes before transferring to a wire rack to cool completely.
