Preheat oven to 350°F (175°C).

Prepare a 9x5 inch baking pan by spraying with non-stick baking spray with flour.

In a food processor, puree bananas and sugar until smooth.

Add eggs and oil to the banana mixture and blend until incorporated.

Add salt, vanilla, milk, baking powder, and baking soda to the mixture and blend.

With the processor off, add flour and pulse 4 times, one second each pulse.

Scrape down the sides of the bowl and pulse one or two more times to incorporate the flour.

Stir in walnuts, chocolate chips, and candied ginger by hand.

Pour batter into the prepared baking pan, scraping the bowl clean.

Bake for 1 hour, or until a tester inserted into the center comes out clean.

Let cool in the pan for 5 minutes before turning out onto a wire rack to cool completely.

Slice and serve. Best enjoyed the next day.

Can be frozen for longer storage.
