Preheat oven to 350 degrees F.
Line a baking sheet with parchment paper or silicone liner.
In a large bowl whisk together flour, oats, baking soda, cinnamon and salt; set aside.
In a separate large bowl, mix together mashed banana, shredded zucchini, honey, coconut oil and vanilla extract until well combined.
Add wet ingredients to dry ingredients and mix until just combined.
Fold in chocolate chips. The dough will be a little sticky.
Drop large spoonfuls on prepared baking sheet and slightly flatten each cookie with the palm of your hand or back of a spoon.
Bake for 13-16 minutes or until cookies start to turn golden brown on the edges.
Allow to cool on baking sheet for 5 minutes before transferring to a wire rack to cool completely.
