P F Chang's Spicy Chicken
2 teaspoons vegetable oil
2 tablespoons chopped garlic (3 to 4 cloves)
3 tablespoons chopped green onions (about 3 onions)
1 cup pineapple juice
2 tablespoons chili sauce
2 tablespoons white distilled vinegar
4 teaspoons granulated sugar
1 teaspoon soy sauce
2 tablespoons water
1/2 teaspoon cornstarch
1 cup vegetable oil
2 chicken breast fillets
1/3 cup cornstarch
Make the sauce by heating 2 teaspoons vegetable oil in medium saucepan. Sauté the garlic and onion in the oil for just a few seconds, not allowing the ingredients to burn, then quickly add the pineapple juice, followed by chili sauce, vinegar, sugar, and soy sauce. Dissolve cornstarch in 2 tablespoons water and add it to the other ingredients in the saucepan. Bring mixture to a boil and continue to simmer on medium/high heat for 3 to 5 minutes or until thick and syrupy. Heat 1 cup vegetable oil in a wok or a medium saucepan over medium heat. While oil heats up, chop chicken breast fillets into bite-size pieces. In a medium bowl, toss chicken pieces with cornstarch until well-dusted. Sauté coated chicken in the hot oil, stirring occasionally, until light brown. Remove chicken to a rack or paper towels to drain for a moment. Pour chicken into a medium bowl, add sauce and toss well to coat chicken. Serve immediately with rice on the side.
