Bring a large pot of salted water to a boil, add the linguini and cook according to package directions. When linguini has finished cooking drain and set aside.
While noodles are cooking, toss cut up chicken pieces with a ½ cup of cornstarch until evenly coated. Heat oil in a deep fryer to 375 degrees. Deep fry chicken bits in batches until golden brown and fully cooked (the internal temperature has reached 165 degrees). Drain on paper towels.
In a bowl whisk together chicken broth, 2 tablespoons of cornstarch, soy sauce, dry sherry, red chili paste with garlic, sugar, red wine vinegar, and sesame oil.
Heat 2 tablespoons of vegetable oil in a wok or fry pan over medium-high heat. Add garlic and stir fry for 15 seconds. Pour the sauce mixture into the pan. Stir in peanuts. Bring to a boil, reduce heat and simmer until thickened and bubbly.
In a serving bowl add the cooked linguini and chicken bits. Add the kung pao sauce mixture. Add green onions and toss everything together.
