In a large bowl, mix together the oats, almonds and chia seeds.
Stir in the almond butter, agave nectar and cinnamon until well combined.
Place the grated zucchini on a sheet of paper towel and squeeze out the excess liquid. Add the zucchini to the oat mixture.
Using 1½ tablespoons (packed) of the mixture for each bite, roll the mixture into bite-sized balls. Using a medium-sized cookie scoop makes this process easier. Also, spray your hands with cooking spray to stop the mixture from sticking.
Place the granola bites on a baking sheet, cover and refrigerate for 1 hour. Serve.
Store the remaining granola bites in an airtight container in the refrigerator for up to 1 week.
