Transfer the chickpea mixture from the food processor into a large mixing bowl. Add the egg, oat flour, 1 tablespoon extra virgin olive oil, salt, black pepper, cumin, red pepper flakes, isot, and grated lemon zest. Knead with your hands for approximately
5-7 minutes until all ingredients are well combined. Ensure the consistency of the mixture is suitable for shaping into meatballs; if necessary, you can add 1-2 more tablespoons of oat flour.
