Prepare Pizza Crust. Combine white wine, lemon juice, 1 tablespoon olive oil, garlic, oregano, basil and pepper in medium bowl. Transfer wine mixture to large resealable plastic food storage bag. Add chicken to bag; seal bag and knead to coat chicken with marinade.
Place in refrigerator and marinate at least 2 hours or overnight.
Remove chicken from marinade; discard remaining marinade. Spray large nonstick skillet with cooking spray; heat over medium heat until hot. Add chicken; cook and stir 12 to 15 minutes or until chicken is golden brown and no longer pink in center. Remove chicken to cutting board.
When chicken is cool enough to handle, cut into 1/2-inch pieces.
Preheat oven to 450°F. Brush dough with remaining 1 tablespoon olive oil. Top with chicken, Boursin cheese, basil and chives. Bake 18 to 20 minutes or until crust is golden brown and cheese is melted.
