Preheat oven to 350°F. Lightly spray a 9 x 5 loaf pan with baking spray or line with parchment and spray with non-stick baking spray.

In a medium bowl, combine flour, baking soda and salt with a wire whisk. Set aside.

In a large bowl, whisk together the oil and sugar until combined. Add eggs and vanilla together and whisk together well, followed by the mashed banana, mixing well.

Add the dry ingredients in with the wet ingredients and mix together with a wooden spoon or rubber spatula until combined without over-mixing.

Add blueberries in a bowl and add a tablespoon of flour and coat the blueberries. Fold in the blueberries and pour batter into the prepared loaf pan; bake in the center rack for about 60 minutes, or until a toothpick inserted in the center comes out clean.

Let the pan cool at least 20 minutes, bread should be room temperature before slicing.
