Place the chicken thighs in the bottom of the slow cooker.
In a small bowl stir together the honey, soy sauce, minced garlic, olive oil, salt, and black pepper until smooth.
Pour the sauce over the chicken and turn the thighs once so both sides are coated.
Cover and cook on low for 6 hours or on high for 3 hours until the chicken is very tender.
About 25 minutes before the chicken is done, bring the 4 cups of water to a boil in a medium saucepan. Add the rice, stir once, then cover and reduce heat to low. Simmer for 18 minutes.
Remove the saucepan from heat and let the rice stand covered for 5 minutes.
Shred or slice the chicken in the slow cooker and stir it back into the sauce.
Spoon the chicken and sauce over the steamed rice and sprinkle with the sliced green onions before serving.
