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

In a mixing bowl, combine the mashed bananas, melted butter, and sugar. Mix well.

Add the beaten eggs and vanilla extract to the banana mixture and stir until combined.

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

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

Fold in the chopped strawberries gently.

Pour the batter into the prepared loaf pan.

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

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