Place the chicken thighs in the slow cooker.
In a small bowl, stir together the honey, soy sauce, minced garlic, and black pepper until well combined.
Pour the sauce over the chicken and turn the pieces to coat them evenly.
Cover and cook on low for 5 to 6 hours until the chicken is tender.
About 20 minutes before the chicken is done, cook the rice according to package directions in a medium pot.
Shred or slice the chicken, then serve it over the cooked rice.
Top each portion with chopped green onions before eating.
