In a skillet over medium heat, heat the water onion, celery, dried oregano, thyme, sea salt, and pepper. Cook for 10-14 minutes, stirring occasionally, until onions and celery are nicely softened (add extra water if needed to prevent sticking). Once onions and celery have softened some, add them to a food processor with the remaining ingredients, and process until the mixture becomes crumbly, and then scrape down the sides of the bowl. Process again to incorporate any larger pieces, and just as mixture becomes sticky and/or forms a ball, stop processor. Refrigerate for at least 1⁄2 hour (chilling will make it firmer and easier to form). Take small spoonfuls of the mixture, about 1 tbsp (using a small cookie scoop is helpful, but otherwise form with your hands, rinsing hands when needed to keep mixture from sticking to your palms). If cooking in a non-stick skillet (see note for oven-baking), add the balls and fry for 5-7 minutes (reduce heat if burning), shifting the pan to turn sides of balls every minute or two to form a golden crust fairly evenly around the balls. Remove, and serve.
