PF Changs: Changs Spicy Chicken

From Top Secret Recipes

2 tsp vegetable oil
2 Tbsp chopped garlic (3-4 cloves)
3 Tbsp chopped green onions (about 3 onions)
1 C pineapple juice
2 Tbsp chili sauce (with garlic will work just as well if you can't find it plain)
2 Tbsp rice vinegar
4 tsp granulated sugar
1 tsp soy sauce
2 Tbsp water
1/2 tsp cornstarch
1 C vegetable oil
2 skinless chicken breast fillets
1/3 C cornstarch

Make the sauce by heating 2 teaspoons vegetable oil in medium saucepan. Saute 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 1/2 teaspoon 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 3-5 minutes or until thick and syrupy.
Heat 1 cup vegetable oil in a wok or 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 remaining cornstarch until dusted.
Saute 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.
