Sift flour, sugar, baking powder, baking soda and salt into a large bowl.
In a separate small bowl, whisk together egg and vanilla extract.
Make a well in the center of the flour mixture, and pour the egg mixture into it. Fold gently.
Add in banana, zucchinis and oil. Fold again very gently. Set aside.
Grease and line an 8” x 4” bread pan with parchment (baking) paper. Make sure the paper hangs over the edges.
Pour bread mixture into the pan. Smooth the top using a spatula. Transfer it to the oven and bake for 30-40 minutes or until a skewer inserted comes out clean.
Leave the bread to cool in the pan for about 10 minutes. Transfer it to a wire rack to cool completely.
