Preheat oven to 350 degrees.
Grind in a food processor in order:
1 cup walnuts (or raw, unsalted sunflower seeds)
3/4 cup minced onion
1 big clove of garlic, peeled
1 stalk celery, without leaves
Combine in a bowl:
2 eggs (or an egg substitute to glue the mixture)
2 tablespoons of fresh parsley (or cilantro), minced
1 cup of bread crumbs
1 teaspoon salt (or use Bragg Liquid Aminos)
Add the ground mixture to the ingredients in the bowl. Mix everything together very well. If mixture is too wet, then add more bread crumbs or nuts to make it firmer. Roll into balls about 1 inch in diameter. Place balls onto an oiled baking sheet. Bake for 45 minutes at 350 degrees. Turn the balls every 15 minutes to cook evenly and to avoid sticking.
Use these in the same way you would serve meat balls. Nobody will know!
