In the bowl of a food processor, combine the drained and rinsed chickpeas, garlic cloves, and rolled oats. Pulse for about 5-10 seconds, until finely chopped. When you press the mixture between your fingers, it should hold together. Transfer to a large bowl along with the dried herbs, salt, nutritional yeast, lemon juice and shredded zucchini. Do not use more than 1 cup of shredded zucchini. Stir together until well-combined. If the mixture is too wet to handle, add a little flour (you can grind extra oats into a flour) or nutritional yeast to help absorb excess moisture.
