Place 6  tablespoons Parmesan cheese and remaining dressing  ingredients in food processor or blender and process  until smooth. Remove 1/4 cup dressing and reserve  remainder for later use.

Preheat grill and lightly coat with oil or cooking  spray. Brush 1/4 cup dressing on both sides of chicken  breasts. Place breasts on prepared grill 4 to 6 inches  from source of heat. Grill 4 to 5 minutes per side,  turning once, or until chicken is no longer pink inside.  Remove to a cutting board and set aside.

Preheat oven to 450°F. Place pizza crusts on a baking  sheet and spread each with garlic & herb cheese,  dividing evenly among crusts. Top with half the pizza  cheese. Cut grilled chicken into 1/2-inch slices and  divide among pizza crusts. Top with tomato, pine nuts,  remaining pizza cheese and remaining 1/4 cup Parmesan  cheese. Drizzle with half the reserved dressing and bake  in preheated oven 10 to 12 minutes until topping is hot,  crust is golden and cheese is melted. Toss lettuce with  remaining dressing and divide among pizzas just before  serving.
