Cut the chicken into bite-sized pieces. Slice the bell pepper into short strips and cut the sugar snap peas in half. Zest and juice the orange. Drain the pineapple, reserving ¼ cup of the juice for the sauce.
Put a medium or large saucepan of water on to boil over high heat for the rice.
In a medium bowl, toss the chicken with the cornstarch until coated.
1 lb boneless skinless chicken breast, 2 tablespoon corn starch
Heat the oil in a large skillet over medium to medium-high heat. Add the chicken, season with salt and pepper and cook until it starts to brown, about 5 minutes.
½ teaspoon salt, ¼ teaspoon black pepper, 1 tablespoon canola oil
Once the water boils, add the rice and cook for 10 minutes (or according to package directions).
2 bags boil-in-bag brown rice
Add the pineapple, bell pepper, and sugar snap peas to the skillet. Cook for 3–5 minutes, until the veggies start to soften.
1 cup red bell pepper, 1 cup sugar snap peas, 1 can pineapple chunks
Stir in the sweet & sour sauce, reserved pineapple juice, soy sauce, orange juice and zest, and red pepper flakes.
½ cup sweet and sour stir fry sauce, ¼ cup pineapple juice, ¼ cup fresh orange juice, zest of one orange, ¼ teaspoon crushed red pepper flakes, ¼ cup soy sauce
In a small bowl, whisk together 1 tablespoon water and 1 tablespoon cornstarch to make a slurry, then stir it into the skillet. Cook for 1–2 minutes, until the sauce has thickened.

Serve over rice garnished with green onions, if desired.
