First cut your chicken thighs into bite sized pieces (if bone in cut around bone into pieces).
Add the flour to a dish or bowl and add in the chicken pieces, toss the piece to coat.
Meanwhile heat your cast iron skillet over medium-high heat and add cooking oil for frying.
Once the oil is hot add in the coated chicken in batches until cooked throughout and is crisp to your liking. (internal temp should be 165 degrees F).
While the chicken is cooking get another skillet going and add the olive oil, the green peppers, and shredded carrots.
Sautee for a few minutes until soft and fragrant.
Next add in the bottle of stir fry sauce plus a little water to the bottle to empty the sauce along with the pineapple chunks.
Heat the sauce until hot throughout then add in the fried chicken pieces to the sauce.
Stir so that everything is coated and serve hot over rice and garnish with sesame seeds if desired.
