Preheat oven to 325° F. Line a cookie sheet with parchment paper.
Combine oats, salt, and cinnamon in a large bowl.
Combine peanut butter, maple syrup/honey, mashed bananas, and zucchini in another bowl.
Stir the wet ingredients into the dry ingredients. Stir in pecans and chocolate chips just until combined.
Using a medium-sized cookie scoop or large spoon, scoop out cookies (about 2 tablespoons each) onto the cookie sheet. Press them down a little to flatten them, since they won't during baking.
Bake for 15-20 minutes, until middle is just set. Cool on the pan for a few minutes and transfer to a wire rack. Store in the fridge or freezer. Best served slightly cooled from fridge.
Freeze For Later: Make sure the cookies are completely cooled. Then, freeze in airtight container or freezer bag, squeezing out as much air as possible.
Prepare From Frozen: Thaw in the fridge, on the counter, or using the defrost setting on the microwave.
