1Preheat oven to 325. Line a loaf pan with parchment and spray with non-stick spray. Set aside.
2In medium bowl, whisk flour, baking soda, baking powder, slat and cinnamon until evenly mixed.
3Microwave frozen spinach for about 1 minute on high. Squeeze out extra water and drain. Process in a food processor with oil until finely pureed. Transfer to a large mixing bowl.
4Into spinach mixture, add zucchini, banana, applesauce, sugar, eggs and vanilla. Mix well. Then add dry ingredients and mix until blended well. Stir in 1/2 c. chocolate chips.
5Pour batter into prepared loaf pan and dot the top with remaining 1/4 c. chocolate chips. Bake for 55-60 minutes. Don't overbake. It will still test a little 'gooey' when it's done baking.
6Let cool in pan on a rack for about 30 minutes. Cut around edges with a knife and carefully lift out onto cooling rack (don't invert or chocolate chips will be smashed).
Let cool, (if you can wait!) cut and serve.
