Start by placing the chicken thighs at the bottom of the crockpot. Season lightly with salt and pepper.
In a mixing bowl, combine the pineapple chunks, diced bell peppers, red onion, soy sauce, honey, apple cider vinegar, minced garlic, and ginger. Mix well.
Pour the mixture over the chicken thighs in the crockpot, making sure they are well coated.
Cover the crockpot and cook on low for 6-7 hours or on high for 3-4 hours, until the chicken is tender and easily shredded.
Once cooked, use two forks to shred the chicken and mix it back in with the sauce and vegetables.
Taste and adjust seasoning if necessary. If you prefer a thicker sauce, you can let it cook uncovered for an additional 30 minutes on high.
Serve the sweet Hawaiian chicken over a bed of jasmine rice and garnish with sliced green onions.
Notes
For a thicker sauce, cook uncovered for an additional 30 minutes.
