Here is an easy recipe with very little fuss or prep. All you will need is a crock pot, spicy yakitori sauce, white cooking wine, and 2 1/2 pounds of boneless, skinless chicken breast. To start, mix 1/4 cup of white cooking wine with 1/4 cup of spicy yakitori sauce and pour into crock pot. Clean your chicken breasts and place into crock pot. Set crock pot to low setting for four hours. At the two hour mark turn your chicken breasts over to let top side soak into the liquid. After four hours, remove and shred chicken (as fine or course as you desire) with two forks and return to crock pot. Add an additional 1/4 cup of spicy yakitori sauce and mix well, let sit in crock pot on warm setting for 15-20 minutes to absorb the juices. Serve with steamed rice. Garnish with green onions (and sesame seeds if desired).
