In a large bowl, toss chicken with 1 tablespoon each soy sauce and cornstarch, salt, and pepper. In another bowl, combine remaining soy sauce and cornstarch, vinegar, ketchup, sugar, and 1/2 cup water; set aside.
Heat 1 tablespoon oil in a large nonstick skillet over medium-high. Cook half the chicken, turning occasionally, until browned and almost cooked through, 4 minutes; remove. Cook the remaining chicken in another tablespoon oil; remove.
Add remaining oil to the pan. Add peppers, white parts of scallions, and garlic; cook over medium-high, stirring, until peppers are crisp-tender, about 3 minutes.
Whisk soy sauce mixture; add to pan. Return chicken; add scallion greens. Cook, stirring, until sauce has thickened and chicken is cooked through, about 2 minutes. Serve immediately over rice, if desired.
Cut the vegetables ahead of time; refrigerate, in separate airtight containers lined with damp paper towels, for up to a day. For sweeter flavor, add up to a cup of cubed pineapple along with the scallion greens in step 4.
This dish has a beautiful presentation. We did not care for the sauce, however...it was bland...should have been sweeter in my opinion...but the dish was gorgeous looking!!
Great meal. Thumbs up from the family who have all lived in Malaysia. Seemed to be too many peppers even with using three.
This was a really good meal. I have to say 5 stars. I served with whole grain rice.
This recipe is awesome. It is always delicious. Definitely add the optional pineapple!
This dish tasted primarily of ketchup. If I can find something to reduce that taste it would be quite good. For a quick meal it is still ok.
AWESOME!! My no-vegetable-eating husband LOVED this dish and asked me to make it again. Great for my 5 year old too!
This was great! I made it this weekend and it was a real hit. I found the pineapple really added the right about of tang to this dish. It was not the same without it.
I made this last night. While not gourmet both of my kids enjoyed it and the picky one even at some pepper. I used yellow and orange peppers. Thanks!
Great recipe. Easy and flavorful. The whole family liked it. Plus I didn't have to run out and buy any odd ingredients to make the sauce - everything was in my pantry!
I'm droolng!!! I find that regular white vinegar works fine too if you don't have rice vinegar on hand. I also always add pineapple chunks in their own juice to the mixture which will cut down on the amount of sugar used.
