Rinse and drain the kidney beans. Put them in a medium bowl and mash them well with a fork. In a medium pan, heat some oil and sauté the onions for 3 minutes. Add the minced garlic and cook for another minute. Add the sautéd onion and garlic to the mashed beans together with the spices, tomato paste, soy sauce, and oats. Put the sunflower seeds in a food processor and pulse until a fine meal is achieved. Add to the bean mixture and combine well. Season with salt and pepper. Form about 12-14 balls.
