Ingredients 2 pounds boneless, skinless chicken breasts, cut into 1 ½-inch chunks 3 tablespoons soy sauce 2 tablespoons cornstarch 1 teaspoon coarse salt ⅓ cup rice vinegar ¼ cup ketchup 4 teaspoons sugar 3 tablespoons vegetable oil 4 bell peppers (green, red, yellow, or a combination), cut into 1-inch pieces 8 scallions, cut crosswise into 1-inch pieces, white and green parts separated 6 garlic cloves, thinly sliced Cooked white rice, for serving (optional) ¼ teaspoon ground pepper Directions 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. Cook's Notes 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. Print
