Step 1

Combine all the ingredients for the sauce in a medium size bowl and stir it until the brown sugar dissolves. (Note: this recipe makes a generous amount of sauce. Reduce the amounts if you prefer less sauce)

Step 2

Add one tablespoon of the sauce to the chicken breast to use as a marinade. The pineapple juice will tenderize the chicken. Meanwhile, prep the vegetables.

Step 3

Heat a pan on medium high heat and add oil to the pan. Add the chicken breast to the pan and stir fry the chicken pieces until it's cooked through (about 3 to 4 minutes). Be careful not to heat the pan too high as the sugar in the marinade can burn easily. Once it's cooked, remove it from the pan and set it aside.

Step 4

Add the red onion, broccoli, red bell pepper, and yellow bell pepper to the same pan and stir fry it until the broccoli is tender but still crunchy (about 3 to 4 minutes).

Step 5

Add the pineapple chunks and cooked chicken breast back to the pan.

Step 6

Stir the sauce once more as the cornstarch can settle. Then add the sauce to the pan and combine everything together. When the sauce starts to simmer, it should turn thick and glossy. Continue to mix everything together for one more minute and then remove it from the heat.

Step 7

Sprinkle the chopped scallions and toasted sesame seeds over the top and serve it over rice.
