Step 1: Make the Sauce
In a medium bowl whisk together soy sauce, tomato paste, Worcestershire sauce, garlic powder, honey, ground ginger, and red pepper flakes until smooth and well combined.
Step 2: Assemble the Crockpot
Place chicken thigh pieces and diced red bell pepper in the bottom of your crockpot. Pour the prepared sauce over the chicken and peppers ensuring they are evenly coated.
Step 3: Add the Pineapple
Drain the canned pineapple chunks reserving the juice. Add the pineapple chunks to the crockpot and gently stir to distribute throughout the mixture.
Step 4: Thicken the Sauce
In a small bowl whisk together the reserved pineapple juice, chicken broth, and cornstarch until no lumps remain. Pour into the crockpot and stir until evenly combined.
Step 5: Cook
Cover and cook on LOW for 5-7 hours or HIGH for 3-4 hours until the chicken is tender and cooked through.
Step 6: Taste and Adjust
About 15 minutes before serving taste the sauce. Add more honey for sweetness or red pepper flakes for heat if desired.
Step 7: Serve
Garnish with sliced green onions and serve over fluffy white rice, quinoa, or cauliflower rice. Enjoy!
