Drain the juice from the canned pineapple into a mixing bowl.
Whisk in the soy sauce, cornstarch, garlic, ginger, sesame oil, brown sugar and red pepper flakes.
Add the diced chicken, pineapple chunks and onion into the bottom of a slow cooker (5 quart or larger slow cooker).
Pour the pineapple juice mixture on top.
Cover and cook on low for 4-5 hours or on high for 2-2.5 hours until the chicken is cooked through (internal temperature of 165 degrees F).
Stir in the red bell pepper for the last 30 minutes of the cooking time until it’s tender.
Serve topped with the green onions and sesame seeds. Enjoy!

Notes
Chicken breasts can be used instead of chicken thighs in this recipe if you prefer. ¼ teaspoon Ground Ginger can be used instead of the fresh ginger in this recipe. I add the red bell pepper at the end of the cooking time so that it doesn’t get too soft. If you're good with soft bell peppers, you can add it in at the beginning of the cooking time and the bell pepper will likely cook down into the sauce. love serving this recipe over rice or quinoa. Refrigerate any leftovers in an airtight container for up to 5 days.
