- Add the chicken breast to your slow cooker and season both sides with salt and black pepper. 
- In a medium bowl, whisk together the soy sauce, brown sugar, rice wine vinegar, sesame oil, cornstarch, water, nori powder, crushed red pepper, ground ginger, and black pepper until smooth. 
- Pour about 1/4 cup of the mixture into the slow cooker and spread it to coat the bottom. Place the chicken on top and pour the rest of the sauce on top. 
- Slow cook the chicken for 3 hours on high or 6 hours on low until the chicken is tender and falling apart. 
- When the chicken is done, shred the chicken with two forks. Serve the chicken teriyaki immediately served on top of a bed of rice or corn tortillas. Drizzle with the pineapple crema (recipe below), sprinkle with fresh cilantro, and enjoy!
