Just make some yourself. It's super easy. Soy sauce, vinegar or lemon juice, diced onions, and chili peppers if you like heat. Most use equal parts soy sauce and vinegar/lemon juice, but adjust to your liking. Every woman I know from Guam has their own 'recipe' but those are the basic ingredients. Enjoy!
